One pond 15

  • A pond dries up every summer and fills again every spring. Write its residents' calendar. Fact: vernal ponds dry up for part of the year and usually have no fish.
  • A pond is smaller than a lake and proud of it. Write its boast. Fact: ponds have been found to hold a greater variety of species than larger lakes or rivers.
  • Describe one pond from above, from the surface and from the bottom, in three short paragraphs. Angle: three viewers: a bird, a floating leaf, a turtle.
  • Draw a circle around one pond and write everything that crosses the line in a day: light, rain, a bird, a kid with a net. Angle: which of them stay?
  • Everything in a pond ecosystem is connected. Write a chain of because sentences that starts with rain and ends with a turtle. Angle: each sentence hands something on to the next.
  • Give the mud at the bottom of a pond a speech. It is tired of being overlooked. Fact: a pond has four zones: the plants, the open water, the bottom mud and the surface film.
  • Sit beside a pond for ten minutes in your mind and write only what moves. Angle: wind counts. So does a shadow.
  • The sun is the first character in a pond's story. Write its morning arrival and who is waiting for it. Fact: plants let energy enter an ecosystem through photosynthesis.
  • Take an inventory of one pond: write every living thing and every non-living thing you can name in it. Fact: an ecosystem is all the living things in a place and the non-living parts they interact with.
  • Write a census report for one small pond: who lives there, who only visits, who is just flying over. Fact: ponds are home to plants, amphibians, fish, reptiles, waterfowl, insects and some mammals.
  • Write a pond's diary entry for the day its ice melts. Fact: when a pond's winter ice melts in spring, sun and wind begin to mix the water.
  • Write how one pond began: a hollow in the ground, rain, and the first living thing to arrive. Fact: a pond can be a simple hollow filled by runoff, groundwater or rain.
  • Write one year of a pond ecosystem in four paragraphs, one for each season. Fact: a pond's size and depth often change greatly with the time of year.
  • Write the edge of a pond as the busiest street in town. Fact: the wetland around a pond's edge shelters wildlife and holds the shore in place.
  • Zoom in on one cup of pond water and write what a very small reporter finds. Fact: a pond's food web is based on free-floating algae and on water plants.

One thing removed 15

  • A tidy gardener removes every dead leaf and fallen log from a wood. Write what goes hungry. Angle: start small: the fungi, the beetles, then whoever eats the beetles.
  • The beavers leave a valley for good. Write the next five years of the pond they made. Fact: a beaver turns its stretch of stream into a pond or swamp.
  • One species is removed from an ecosystem and almost nothing changes. Write the puzzled scientist's notes. Fact: losing a species much like the ones still present tends to have only a small effect.
  • One tree falls and takes away the shade. Write the race among the small plants below for the new light. Fact: shading by other plants is a major limit on a plant's photosynthesis.
  • Take every bee out of a meadow for one summer. Write the meadow the next spring. Fact: bees carry pollen from flower to flower, which plants need to make fruit and seed.
  • Take the elephants out of a savanna and write the same view fifty years on. Fact: elephants destroy trees and make room for grass. Without them much savanna would turn to woodland.
  • Take the parrotfish away from a coral reef. Write what grows. Fact: parrotfish feed on the algae that compete with coral.
  • Take the prairie dogs out of a prairie. Write the notice the burrowing owls receive. Fact: prairie dog burrows give nesting places to burrowing owls and mountain plovers.
  • Take the rain away from an ecosystem for one summer and write its report card in the fall. Fact: a drought is one of the year-to-year swings an ecosystem lives through.
  • Take the smallest living thing you can think of out of a forest, and argue that it matters more than the biggest. Fact: a keystone species has a far larger effect than its numbers would suggest.
  • Take the starfish out of a rocky tide pool and write what the pool looks like ten years later. Fact: when starfish were removed from one shore, mussels crowded out most other species.
  • Take the wolves out of a wide valley. Write what the grazing animals do first, and what the young willows notice. Fact: with the gray wolf gone from one great park, plant eaters over-grazed the young woody plants.
  • Take the woodpeckers out of a wood. Write the housing shortage that follows. Fact: the holes woodpeckers make in trees are later used as homes by other birds and mammals.
  • Write a game of pick-up sticks as an ecosystem: each stick is a species, and one must not be touched. Angle: which stick is it, and how do the players find out?
  • Write an ecosystem as a stone arch, and name the one stone nobody should pull out. Fact: a keystone species is named for the keystone of an arch, which collapses without it.

Who needs whom 15

  • A bean plant and the bacteria on its roots run a shop together. Write a day behind the counter. Fact: bacteria on the roots of bean-family plants supply nitrogen in return for carbohydrates.
  • A bee and a flower write each other thank-you notes. Write both. Fact: bees take pollen and nectar as food and carry pollen on to other flowers.
  • A caterpillar rolls a leaf into a shelter and moves out. Write the next three tenants. Fact: the leaf shelters caterpillars make are also used by other creatures, at once or afterward.
  • A small fish lives among the stinging arms of a sea anemone. Write what each tells its friends about the other. Fact: the anemone protects the fish from predators. The fish drives off fish that eat anemones.
  • Count everything that some other living thing did for you before breakfast, and write the list as a thank-you. Fact: ecosystems give people food, clean air and water, and the pollination of crops.
  • Every living thing in a meadow hands the others a bill. Write the meeting where they find the bills cancel out. Angle: who owes the sun?
  • Interview a plant about what it needs from the sun, the soil, the rain and the animals, in that order. Angle: its answers get shorter as the needs get bigger.
  • Two animals that need each other have a falling-out. Write what it has cost them both by Friday. Angle: neither will say sorry first.
  • Under the forest floor a tree and a fungus trade. Write the deal as a market scene. Fact: the plant gives the fungus carbohydrates, and the fungus passes phosphate back to its roots.
  • Who needs whom on your own block? Write a web of five living things within a short walk of your door. Angle: one tree, one bird, one insect, one person and one you had to look for.
  • Write a contract between a berry bush and the bird that eats its berries. Fact: plants use fruits to get animals to carry their seeds away.
  • Write a letter from a coral to the tiny living things inside it that catch the sunlight. Fact: corals get food from sunlight with the help of microorganisms living in them.
  • Write a poem called Mutual, in which each stanza is a pair of species that help each other. Fact: mutualism is a tie between species in which each one benefits.
  • Write a want ad placed by a flower that needs a pollinator. Angle: what it offers, what it asks, what hours.
  • Write the web of needs around one backyard bird feeder: who comes, who waits below, who watches them all. Angle: do not forget whoever fills it.

A new arrival 15

  • A storm carries a few lizards on a raft of branches to an island that has none. Write the island's first year with them. Fact: species also reach new places without people, carried by storms or on floating rafts.
  • A streetlight is put up beside a dark marsh. Write what changes at night. Angle: who comes to the light, and who stays away from it?
  • A volcano leaves an island of bare rock. Write the arrival of the very first living thing. Fact: life's slow return to ground left with no plants or soil is called primary succession.
  • Not every newcomer is a villain. Write about a new arrival that the old residents of an ecosystem end up glad of. Fact: some introduced species have little or no bad effect and fit in well.
  • Two old residents of a meadow greet the same newcomer, one with a welcome and one with a warning. Write both speeches. Angle: which of them turns out to be right?

  • Write the diary of a burned hillside's first five springs. Fact: recovery after a forest fire is called secondary succession, and it is the faster kind.

How it works

These ecosystems writing prompts take one living thing out of a place and ask what happens next. Others take stock of a single pond, pair up the species that need each other, and watch a newcomer settle in.

Writing prompts about ecosystems: one thing removed

Fifteen prompts remove something and write what follows. The prairie dogs leave a prairie, the parrotfish leave a reef, the beavers leave the pond they made. Several rest on what was recorded when it really happened: with the starfish gone from one shore, mussels crowded out most other species.

One pond

A pond is small enough to hold in one piece of writing. Take its inventory, living and non-living. Give the mud a speech. Write the day the ice melts, or the calendar of a pond that dries up every summer and has no fish.

  • Remove one thing only. With two changes at once, nobody can tell which did what.
  • Follow the change three steps out. The third step is where the surprise is.

Questions and answers

What is a good writing prompt about ecosystems?

Take every bee out of a meadow for one summer, then write the meadow the next spring. Or a tidy gardener removes every dead leaf and fallen log from a wood: write what goes hungry.

What is an ecosystem?

All the living things in a place together with the non-living parts they interact with, such as soil. Energy comes in through plants, and decomposers turn the nutrients in dead matter back into a form plants can use.

What is a keystone species?

A species with a far larger effect on its surroundings than its numbers suggest. The name comes from the keystone of an arch, which collapses without it. The beaver, which turns a stream into a pond, is one.
