A. Trophic relationships between plants and animals do not exist as a simple chain, but tend to be more elaborate and interwoven as a food web.
B. In food webs, different herbivores may feed on the same plant. Also, the same species of herbivore may feed on different plants.
C. Consumers which feed on the dead remains of plants and animals are called detritivores.
D. In food webs, a typical food chain consists of approximately 6 organisms.
参考答案: D
本题详细解析:
Explanation: The length of food chains tends to be shorter than 6 organisms, even including parasites and detritivores. When energy is passed from one organism to the next, most of the energy is generally lost as heat which means that less and less energy is available to higher trophic levels. All other statements are true.
