In a healthy ecosystem, which trophic level should
have the most energy? Why? *WILL MARK BRAINLIEST*
Answer:
Producer(plants)
Explanation:
They can produce there own energy and they help all of the other animals stay alive.
in a healthy ecosystem, the trophic level that should have the most energy is the producer.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem.Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities.More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy will be in the producers as the lowest trophic level.Therefore, in an healthy ecosystem, the trophic level that should have the most energy is the producer.

Ten fish have lived in a 10-gallon fish tank for 6 months. However, within 2 weeks of adding 6 new fish, the population of fish drops to 7
fish. Which most likely accounts for this drop in the fish population?
A. The additional fish increased the water level.
B. The additional fish reduced the space per fish.
C. The additional fish increased the water temperature.
D. The additional fish reduced the carbon dioxide levels.
Answer:
I think it's D
Explanation:
Although space per fish is important, and may even be correct, I found D to be the most logical answer as each fish would need the same amount of carbon dioxide or the unbalance would cause a decrease in population.

Explanation:
The correct word would be pollution.
Pollution can be described as the presence of ecologically harmful substances in the environment.
Littering the ground is considered pollution because it is harmful to the environment in the long term. Harmful chemical in water is outrightly considered pollution because this will hurt the organisms living in the water and rendered the water unusable to those around it.

Why are proteins NOT a primary source of energy in living organisms (carbohydrates are
primary, lipids are energy storage...)?
Answer: Energy Production
The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

Nitrogen in the atmosphere exists in the form of _____.
NO2
NO3-

Explanation:
Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, or atmospheric nitrogen, can also be found in the soil. In addition to dinitrogen, other inorganic and organic forms exist in the soil as well.
