In a food pyramid, there is typically less biomass at the top (i.e., there are very few individual tertiary consumers, whereas there are numerous individual producers). In three to five sentences, explain this phenomenon, citing evidence relating to energy flow and how plants support ecosystems.
It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
The energy transfer in ecosystems:It is found that only 10% of the energy stored as biomass in a trophic level is carried forward to the next trophic level. This is called the 10% rule, due to this rule, the number of trophic levels an ecosystem can support is limited.
As one goes up in the food chain, only 10% of the energy is passed on to the next level, that is, about 90% of the energy is lost in the form of heat. At the bottom of the trophic level, there are producers, that is, plants, they get their energy from the Sun.
Further the plants are consumed by the primary consumers, and the energy is passed on. However, in the process, only 10% of the energy is passed on and the rest is lost in the form of heat. Further the primary consumer is consumed by the predator, which comes at the top of the food chain.
During the consumption of primary consumer, the same 10% energy is passed on and the rest is lost. This process continues and the energy is lost in the form of heat. With less energy at the top of the trophic level, only few individuals can be supported. This is the reason of less predators in comparison to prey.
Thus, it is the 10% rule, which results in lesser number of tertiary consumers in comparison to producers.

It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
Briefing:Only 10% of the energy produced by primary producers is used by consumers; the remaining 90% is wasted. Let's assume that a fox consumed a rabbit that had previously consumed grass and had retained 10% of its energy. As a result, the fox will only receive 1% because 10% of 10% is only 1%, and this will continue to trickle down to tertiary customers. In order for primary consumers to exist and for secondary consumers to be able to survive without primary consumers, ecosystems need plants, or primary producers. (Equally true for tertiary consumers).
Who is a Tertiary consumer?Quaternary consumers pounce on tertiary consumers. These quaternary consumers are frequently the apex predators, which indicates that their ecology is devoid of any predators. Animals like lions, polar bears, sharks, and hawks are some examples of quaternary consumers.

Answer:
Competition will occur between organisms in an ecosystem when different species try to use the same resource, causing the resources carrying capacity is reached. Animals compete for food, water and space to live. A limiting factor would stop this from happening, making competition in an ecosystem go down.
Answer:
Competition occurs when an ecosystem reaches it's carrying capacity. When a ecosystem reaches it's carrying capacity there are limiting factors such as scarce resources and limited habitats.

Which two body systems maintain the level of glucose in the blood?
Answer:
The endocrine functions of the pancreas and liver coordinate efforts to maintain normal blood glucose levels.
The pancreas and liver regulate the level of glucose in the blood.
What is diabetes?Maintaining blood glucose is important for the body. The body needs glucose for the production of energy. The inability of the body to regulate blood glucose results is a result of diabetes. The blood glucose in our body is maintained by two hormones.
Insulin reduces the amount of glucose in the blood and glucagon increases the amount of glucose in the blood. Insulin and glucagon work together, in people without diabetes to maintain the blood glucose level of the body.
But in people affected by diabetes, insulin has either stopped working or insulin production by the body is inadequate compared to the body's requirements.
In type 2 diabetes, insulin production is low and in type 1 diabetes, there is resistance to insulin.
Insulin and glucagon are produced by the islets of Langerhans cells of the pancreas. In excess of insulin, the liver stores glucose from the blood, and in excess of glucagon, glucose is released by the liver into the blood.
Therefore, the pancreas and liver regulate the level of glucose in the blood.
