Law of conservation of energy Cellular respiration Photosynthesis Food chain 8 / 15 Mushrooms get energy from breaking down dead organisms. Are mold and mushrooms the same type of organism? No, because they look different from each other. Yes, because they both get energy from breaking down dead organisms. No, because they are different species.

Wildflowers and Grass Rabbit and Mouse Snake and Hawk Grass and Mouse 11 / 15 Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach? Producers are limited by consumers. Plants are not infinite in number. Energy is lost at each trophic level. Carnivores are too large to be eaten. 12 / 15 It is a detailed description of the species within a community and their relationships with each other; it shows how energy is transferred up food chains that are interlinked with other food chains.
