Food chain and food web Quinto de Primaria

Food chains.

Every living thing needs energy from other living things to live. Animals obtain energy from the food they eat, for example, rabbits eat grass, the snake eats rabbits and the eagles eat snakes.

Plants use nutrients from the soil, water and sunlight to get energy in a process called photosyntesis (during the nights).

Energy is necessary for them to grow.

A food chain shows which living things feed on other to get the energy they need.

Food webs.

A food web consists of all the food chains that we can find in an ecosystem. Each living thing in an ecosystem is part of multiple food chains. The energy travels through the different chains and living things and the ecosystem survives.
