An ecosystem is made up of living things like plants and animals as well as non-living things like air, water, and soil. A population is a group of the same species in an area while a community includes all populations in an ecosystem. Producers like plants use photosynthesis to make their own food while primary consumers eat producers. Secondary consumers eat other animals and decomposers break down dead organisms and waste. Food chains show single paths of energy transfer while interconnected food webs display the complex feeding relationships in an ecosystem. Deserts are dry ecosystems while savannas and grasslands differ in rainfall and tree coverage. Urban ecosystems include parks and developed areas inhabited by urban-adapted plants and animals.
