Learn about producers, primary consumers, secondary or tertiary consumers, apex predators, and decomposers and the roles they play in food chains like.
A food chain shows how energy is transferred from one living organism to another via food it is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.
Food webs and food chains worksheet 1 look at this food chain lettuce greenfly ladybird thrush cat a what does the arrow mean in a food chain b name the producer in the food chain c name the third trophic level in the food chain d name the tertiary consumer in the food chain e what is the ultimate source of energy that drives the food chain _____ 2 look at these food chains. A food chain differs from a food web, because the complex network of different animals' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time natural interconnections between food chains make it a food web. The food web is an interconnected network of different food chains for example: in a terrestrial habitat, grass is eaten by a grasshopper or a caterpillar, the grasshopper or the caterpillar is eaten either by a frog or a wasp, and the frog can be eaten by a snake or an eagle.
Food chains and food webs and/or food networks describe the feeding relationships between species in a biotic community in other words, they show the transfer of material and energy from one. Food chains and food webs food chains all living organisms (plants and animals) must eat some type of food for survival plants make their own food through a process called photosynthesis using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food.
Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems energy transfer between trophic levels is inefficient—with a typical efficiency around 10.
