Why is there a decrease in available energy at each successive trophic level in an energy pyramid?*1 pointOrganisms release energy as heat during metabolic processesOrganisms store energy in their bodies as biomassOrganisms use energy for growth and reproductionOrganisms transfer energy to predators through consumption

Which of the following best explains why terrestrial trophic pyramids usually do not have levels higher than tertiary consumers?ResponsesTertiary consumers are the largest organisms in an ecosystem and require the most space to survive.Tertiary consumers are the largest organisms in an ecosystem and require the most space to survive.Plants can only perform photosynthesis during the day, so tertiary consumers cannot get enough energy from consuming plants.Plants can only perform photosynthesis during the day, so tertiary consumers cannot get enough energy from consuming plants.A large proportion of energy is lost as heat as it is transferred up the pyramid, so there is not enough energy available to support another level.A large proportion of energy is lost as heat as it is transferred up the pyramid, so there is not enough energy available to support another level.Tertiary consumers are often indicator species and are the first to be affected by environmental disturbances.

While nutrients cycle through environments, energy flows through an environment in one direction. This flow of energy is often shown with an energy pyramid, such as the one below.Trophic Levels by Saric (CC BY-SA 3.0)Which of the following correctly states the percentage of energy lost between each trophic level on the energy pyramid and what that energy is lost as?Elimination ToolSelect one answerA90%90%, exercise.B10%10%, exercise.C90%90%, heat.D10%10%, heat.

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

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.
