Answer:

At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.

Analyze the pyramid representing the energy flow through an ecosystem. Select the phrases that accurately describe the flow of e
saveliy_v [14]

In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.

<h3>Energy pyramid in the ecosystem</h3>

The producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.

The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.

Thus, one can effectively conclude that:

  • Herbivores have more energy available to them than carnivores.
  • There are fewer tertiary consumers than secondary consumers.
  • Soil organisms recycle nutrients but not energy back into the ecosystem.

MakcuM [25]

<u><em>Ecology</em></u><em> is the study of interactions among organisms and their environment including its living and nonliving parts.</em>

Answer: A. Ecology

Ecology is learned at numerous levels, including creature, populace, network, biological system, and biosphere. Water accessibility is a case of an abiotic, or nonliving, factor that can influence dispersion of creatures.

Accessibility of supplements given by different life forms is a case of a biotic, living-creature related, factor that can impact appropriation.
