Ecosystem Quiz

What process do plants in an ecosystem use to get energy from the sun?

• Respiration

• Photosynthesis

• Decomposition

• Transpiration

What are producers in an ecosystem?

• Animals that eat plants

• Plants that produce food

• Decomposers that break down matter

• Rocks that form soil

What role do decomposers play in the nutrient cycle?

• They produce food for plants

• They break down dead matter and release nutrients

• They consume plants and animals

• They provide sunlight for photosynthesis

Where are tropical rainforests located?

• Between 30 degrees north and 30 degrees south of the equator

• Between 5 degrees north and 5 degrees south of the equator

• At the poles

• In desert regions

Why is the area near the equator very hot?

• Because the sun is always directly overhead

• Due to high altitude

• Because of constant rainfall

• Due to strong winds

What is an example of a large ecosystem?

• A small pond

• A tropical rainforest

• A single tree

• A desert

What allows rapid chemical weathering of bedrock in the rainforest?

• Low humidity

• High humidity

• Cold temperatures

• Lack of sunlight

What is the effect of high precipitation on the soil in the rainforest?

• It dries the soil

• It leaches nutrients from the soil

• It freezes the soil

• It compacts the soil

What is the role of plant roots in the rainforest water cycle?

• They absorb sunlight

• They take up water from the ground

• They produce oxygen

• They store carbon dioxide

What is a characteristic of the rainforest's nutrient cycle?

• Slow decomposition

• Rapid decomposition

• No decomposition

• Decomposition only in winter
