List a 12 organism food chain?

Answer 1

• Producer - usually a green plant that produces its own food by photosynthesis
• First-order Consumer - the organism that eats the producer
• Second-order Consumer - the organism that eats or derives nutrients from the first-order consumer
• Herbivore - a plant eater
• Carnivore - an organism that obtains nutrients from the blood or flesh of an animal
• Omnivore - an organism which eats both plant and animal matter
• Scavenger - an consumer that eats dead animals (e.g. crab)
• Detritivore - a consumer that obtains its nutrients from detritus
• Decomposer - an organism such as bacteria and fungi that breaks down dead organisms and their wastes
• Trophic Level - A trophic level is each level in a food chain. Matter is always 'lost' as heat energy at each trophic level.
• Basal Energy Requirement (B.E.R.) - the amount of energy used by an organism's body just to keep alive, when no food is being digested and no muscular work is being done
• Food Web - a network of interrelated food chains in a given area
