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.
