Answer:
an association of different organisms forming a closely integrated community.
Explanation:
A biocenosis thus refers to a group of interdependent organisms living and interacting with each other in the same habitat. It may also pertain to a group of fossil species that are typically found together in the same habitat or site.
Biocenosis, is a community of Biotic beings, with life, of an ecosystem, where the different individuals are organized in populations through trophic relationships and also interact with their environment.

What is photosynthesis?
A. growing flowers from seeds
B. using light to make high-energy
carbohydrates this is answer
C. using fertile soil to grow
horticulture
D. water absorption from plants
Answer:
B.
Explanation:
Photosynthesis is basically plants using sunlight (or any light) to make 'food'.
Plants, algae, and cyanobacteria that contain chlorophyll engage in the most prevalent and important type of photosynthesis. These organisms absorb solar energy and transform it into chemical energy contained in the molecules of carbohydrates by using carbon dioxide and water. Thus, option B is correct.
What are the process involving in photosynthesis?The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
The photosynthetic cycle contains three stages, which are as follows: Light energy is absorbed by chlorophyll, which then divides water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. Carbon dioxide is reduced, which results in the creation of carbohydrates.
Therefore, using light to make high-energy carbohydrates.

Which could cause a
change to the carrying
capacity of a species in an
ecosystem?
A. seasons changing
B. continuous rotation of resources
C. more predators
D. consistent rain falls
The carrying capacity of a species in an ecosystem is the continuous rotation of resources. Option B.
As abiotic or biotic factors change so does the carrying capacity. Natural disasters can destroy ecosystem resources. When resources are destroyed, ecosystems can no longer support large populations. This reduces the payload. Increased food production through improved agricultural practices control of many diseases with modern medicine, and the use of energy to render historically uninhabitable areas.
Earth's habitable is an example of something that can expand its carrying capacity. Altering ecosystems can increase the carrying capacity of some species, as other species are overwhelmed and populated while others are dramatically reduced due to hunting. Carrying capacity is the maximum number of individuals in a population that the environment can support.

what is the net gain of energy when going from the bonds broken to forming new bonds in new proteins?
While a gram of protein has four calories, the same as a gram of carbohydrates, the body does not readily use protein as a fuel source. Around 5% of the daily energy needs are met by protein on an average day.
What is the involvement of protein in energy production?Because a large portion of the energy required to build complex organic food molecules like sugars, lipids, and proteins is physically stored inside the chemical bonds that keep them together, these molecules are abundant sources of energy for cells.
In some reactions, energy is absorbed because more energy is needed to break bonds than is created when new bonds are formed.
Therefore, When bonds are broken, energy is absorbed, and when bonds are formed, energy is evolved.

Erosion is the geological technique wherein earthen substances are worn away and transported with the aid of using herbal forces together with wind or water. A comparable technique, weathering, breaks down or dissolves rock, however does now no longer contain movement. Erosion is the alternative of deposition, the geological technique wherein earthen substances are deposited, or constructed up, on a landform. Most erosion is accomplished with the aid of using liquid water, wind, or ice (commonly with inside the shape of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking area. The brown colour suggests that bits of rock and soil are suspended with inside the fluid (air or water) and being transported from one area to another.

Overexpression of growth factors or the absence of suppressor proteins can lead to rapid cell division.
How the cell cycle allows cell division before returning to normal?The study of the cell cycle focuses on the apparatus that regulates the timing and frequency of DNA duplication and cell division during the mitotic (M) phase, the cell divides its duplicate DNA and cytoplasm to make two new cells. M phase involves two distinct division-linked processes such as mitosis and cytokinesis. A cell cycle is a series of events that takes place in a cell as it fattens and divides. A cell spends most of its time in what is called interphase, and through this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and concluded its division.
So we can conclude that the division cycle of most cells comprises four processes such as cell growth and DNA replication.
