A. Producers; Autotrophs A. The sun Q. In ecology what is meant by a trophic level? Q. What is an ecosystem? A. A community of living organisms A. The position of an organism in a interacting with one another and food chain their environment Q. What is a food web? Q. Explain the term biosphere. A. The part of the planet where life occurs A. Interconnected food chains; More than one species at each trophic level Q. What is a habitat? Q. True or False. Herbivores normally live long lives. A. The place where an organism lives Q. In ecological studies what are abiotic factors. A. False Q. Organisms capable of making their own food are known as … A. Non-living features that influence the distribution of organisms A. Producers Q. Where in a food chain are primary producers found? Q. Explain the term edaphic. Page 1 of 4 A. Relating to the soil A. First level Q. True or False. The term abiotic refers to the living factors in an ecosystem. Q. Why are most food chains short i.e. only consist of a few trophic levels? A. FALSE A. Large energy loss from one level to next; Small energy transfer Q. Give an example of an abiotic factor that influences the distribution of a named plant in an ecosystem. A. e.g. Climatic; Edaphic; etc. Q. Give an example of an edaphic factor. A. Particle size; Soil type; pH; Air content; Water content; Mineral content; Humus content Q. What term is used to describe organisms that feed on primary producers? A. Primary consumer(s); Herbivore(s) Q. What deduction may be made if the organisms at the start of the chain are less numerous than those that feed upon them? A. Producers are large; Primary consumers are parasites Q. Can a parasite be the first member of a food chain? Q. In ecological studies what are biotic factors. A. Living features that influence the distribution of organisms Q. What is meant by a pyramid of numbers? A. No. They are not producers Q. Energy enters food chains in the form of light. In which form do you think most energy is lost from food chains? Page 2 of 4 A. The numbers of organisms at each trophic level A. Heat Q. Give an example of a biotic factor that influences the distribution of a named animal. Q. Name the process that takes place in plants in which the sun’s energy is converted to a usable form. A. Predator (fox) influences distribution of rabbits A. Photosynthesis Q.
