The predator can also decompose nutrients to recycle them. The presence of an owl prevents prey species from overgrazing ecosystems. The predator owl eats rats and mice, frogs and snakes among other things. All living things on Earth need the sun to provide food, and plants use photosynthesis for food production.Ĭonsider the example of the great-horned Owl to understand the food chain. All food chains start with energy from sunlight. Your students will be able to identify different members of the food chains with the help of the food chain science activity.Ī simple food chain allows you to compare plants and animals at the next level, such as lions, giraffes, and trees. Omnivores are animals that eat both meat and plants. Carnivores are the last members of the food chain and eat both meat and plants.
The first two food chains are herbivores and they are the main consumers of plants.
Photosynthesis is a process that converts sunlight's energy into food. Green plants are the first part of the food chain.
