Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

When plants undergo photosynthesis, they take in water and other nutrients from the soil and carbon dioxide from the air to prod

Vinil7 [7]

Answer:

In an ecosystem photosynthetic plants act as producers wheres other organism act as consumers.

Explanation:

Green plants undergo photosynthesis to produce their own food as a result they are called producers and are placed in the first tropic label of energy pyramid.

The other organism that intake green plants are called primary consumers for example grasshopper. The primary consumers are placed in the second tropic label of energy pyramid.

The other consumers are termed as secondary consumers or primary carnivores that feed on primary consumers For example Snake because it eats grasshopper and is placed in the third tropic label.

Finally the tertiary consumers or secondary carnivores consumes secondary consumers to intake energy from them.For example Hawk eats snake,as a result hawk act as secondary carnivores and are placed in the top of the energy pyramid.
