How do plants depend on animals to carry seed?

How do animals depend on plants?
• Plants produce oxygen. • Plants are eaten by producers who
would not survive without them. • Plants that are no longer living are
eaten by decomposers. • Plants are the main source of energy
entering food chains.

• Natural events such as changes in weather and climate (e.g., hurricanes, tropical storms, drought) can cause ecosystems to change. Human activities such as air pollution, cutting down forests and digging for resources in Earth’s surface can cause ecosystems to change.
• Laws are made to limit pollution and make hunting certain animals or picking certain plants illegal.
What causes ecosystems to change? How can people protect ecosystems?
