Plants take in carbon dioxide and produce oxygen, which animals need to breathe. Animals eat plants or other animals, and their waste helps plants grow. Rivers carry water to plants and animals, while trees provide shade and homes. If one part is hurt, others will be affected. For example, if we pollute rivers, fish will die, and birds that eat fish will go hungry. So we must protect every part of the ecosystem. 1. What do plants produce for animals? A. Carbon dioxide B.

When we go hiking, we shouldn’t leave rubbish, but we can pick up litter left by others. Plants need water, so we can water them during dry weather.
