In food web, each successive trophic level has?  A. Increased total energy  B. Less total energy content  C. More total energy content  D. Non estimated energy content

Write the scientific term: 1. A diagram shows the amount of energy that moves from one feeding level to another in a food web. (............................) Put (true) or (false): 1. There is a limited number of levels in a food web or an energy pyramid. ( ) 2. Each level has less energy available in the energy pyramid than the level below. ( ) 3. Only about 50 percent of the energy at one level of a food web is available to the next higher level. ( ) 4. Producers can be found at the base of the energy pyramid. ( )

Select all the correct answers.In an aquatic ecosystem, the fishing of a particular fish species increased. This fish species is a secondary consumer in an energy pyramid. The fishing of the species led to a decrease in its population. In which two ways will this affect the food web? The higher levels in the pyramid will receive more energy. The higher levels in the pyramid will receive less energy. The lower levels in the pyramid will have less predation. The higher levels in the pyramid will receive no energy at all. The lower levels in the pyramid will receive less energy.

Losses of usable energy between successive trophic levels in an ecosystem are best accounted for by which of the following?ResponsesThe first law of thermodynamicsThe first law of thermodynamicsThe second law of thermodynamicsThe second law of thermodynamicsThe law of conservation of matterThe law of conservation of matterThe process of ecological successionThe process of ecological successionLimiting factors in the ecosystem
