Ecology and Biomes Guide

Read the field notes and biome descriptions to investigate how living things interact with their environments. Answer each question in complete sentences when asked.

Field Notes: Cedar Prairie

A small prairie ecosystem includes grasses, wildflowers, rabbits, grasshoppers, snakes, hawks, fungi, and bacteria. Sunlight helps plants make food. Rabbits and grasshoppers eat plants. Snakes may eat grasshoppers or rabbits, and hawks may eat snakes or rabbits. Fungi and bacteria break down dead organisms and return nutrients to the soil. The prairie also has nonliving parts, including soil, water, air, and sunlight. Together, its living and nonliving parts form an ecosystem.

1.In the Cedar Prairie field notes, name one living part and one nonliving part of the ecosystem.
2.Which statement best explains how a prairie plant gets energy to grow?
  • It gets energy by eating grasshoppers.
  • It uses sunlight to make its own food.
  • It gets energy from the soil alone.
  • It catches and eats small animals.
3.Use the field notes to complete this food chain: sunlight → grass → rabbit → _____. Choose an organism that could fill the final spot.
4.A prairie team finds dead leaves and a dead insect. Which organisms in the field notes help break them down, and why does that matter?

Biome Clues

A biome is a large region with a characteristic climate and typical communities of plants and animals. Climate includes long-term patterns of temperature and precipitation. Tropical rainforests are warm and receive abundant rain, supporting dense vegetation. Deserts receive very little precipitation and typically have sparse vegetation and dry, sandy or rocky ground. Arctic tundra regions are very cold, have permafrost, and have a short growing season.

5.Which biome is most likely to have permafrost and a short growing season?
  • Tropical rainforest
  • Desert
  • Arctic tundra
6.Which of the three biomes described is generally driest? Give one clue from the descriptions that supports your answer.
7.True or false: A biome and an ecosystem mean exactly the same thing. Explain your choice.
8.Imagine a long drought reduces the prairie grasses. Predict one likely effect on rabbits and explain the connection.
9.Which action is most likely to damage a prairie ecosystem by removing habitat?
  • Protecting native grasslands
  • Planting native wildflowers
  • Converting prairie land into roads and buildings
  • Keeping litter out of streams
10.The prairie team can fund one project. Choose a helpful action—protect native grassland, plant native species, or reduce pollution—and explain how it could support biodiversity.
