In a forest food chain, what is the connection between the sun and a tree?

• The sun helps chlorophyll turn oxygen into carbon dioxide.

• The tree shades animals from the sun and gives them nutrients.

• The sun heats up the ground so the tree's roots can take in water.

• The tree uses the sun's energy to make food through photosynthesis.

Which of these happens during the time a fallen log is decomposing?

• The fallen log slowly begins to die.

• The fallen log continues to produce food.

• The materials in the log combine into new, complex parts.

• The materials in the log are broken down into smaller, simpler parts.

Why are bacteria shown at the end of a food chain?

• They are producers, and make their own food.

• They are consumers, and feed off of dead organisms.

• They are decomposers, and break down dead organisms.

• They are consumers, and the smallest organisms on the food chain.
