Plants and animals that need one another in an environment form an ecosystem. All ecosystems have energy pyramids that show the exchange of energy from one food source to another. Biomes are areas of the Earth that have their own climate and characteristics. Ecosystems all over the world are in danger due to pollution, hunting, and other factors. By conserving water, recycling, and reducing pollution, we can help protect Earth's ecosystems and biomes.
