Why is far less energy available to top predators than to first level consumers in a food web?

Biology

Sedaia [141]3 years ago
8 0

Answer and Explanation:

Most of the food eaten by herbivores(primary consumers) passes through the digestive tract as undigested matter that is removed as faeces. Most of the absorbed food materials are used in respiration to release energy. Only a small proportion of the consumed food is incorporated into tissues of the consumer while the rest is lost through excretion. Only the food incorporated into the tissues can be passed on the top predators and secondary consumers.

Gelneren [198K]

Answer:

It will result /lead to side effect that could be fatal and life threatening since its inactivation time is longer thus the effect of the large dose will be more pronounced and long lasting.

Explanation:

An hormone agonist is a compound/molecule that can bind to the hormone specific receptor leading to the activation of the endocrine gland, the biosynthesis of secreted hormone and the eliciting the physiological effects of such hormone. Androgenic anabolic efficacy  of steroids is usually goverened by their receptor binding andspecificity and their biotransformation from active to inactive form. Possible  side effect include elevated blood pressure, voice deepening, decease libido, early myocardial infarction and many more

How would the cycle be different if there were no water on earth?
Luda [366]

Answer:

What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Explanation:

The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:

water.usgs.gov

water.usgs.gov

So what would happen if there were no condensation stage?

The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.

Without clouds, I foresee a few things happening:

From clouds come rain. With no clouds, there would be no rain.

Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.

Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.

And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
