This is because the level of energy decreases throughout the food pyramid.
At the beginning with producers, they contain the most energy or 100%. However, once they are consumed, the consumer loses 90% of the energy. Thus, primary consumers only get 10% of the energy, secondary consumers only get 1% and so on and so forth higher.
Because of the lack of energy being passed along within the food pyramid, higher order consumers (typically carnivores) must have a lot of prey to consume, but this also means competition. Therefore, higher in the ranks, there is more competition which leads to smaller populations.
Hope this helps!
Answer:
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.

Explanation:
because the energy gets smaller as the predators increase.
I believe that spermatocele is a cyst that develops in the epididymis and is filled with a milky fluid containing sperm. It is an abnormal sac that develops in the epididymis which is a small, coiled tube located on the upper testicle that collects and transports sperm. A spermatocele is usually painless and filled with milky or clear fluid that might contain sperm.
Defenses against herbivory and adaptations related to wind dispersal of pollen are likely to cause human health problems.
<h3>
What are defense responses against herbivores?</h3>
The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores.
Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves).
They discourage animals by causing physical damage or by inducing rashes and allergic reactions.
Some Acacia tree species have developed mutualistic relationships with ant colonies: they offer the ants shelter in their hollow thorns in exchange for the ants’ defense of the tree’s leaves
