The answer is down below.
Explanation:
Estuaries
-More than 80 percent of all fish and shellfish species use estuaries as primary habitat or as a spawning or nursery ground.
-Estuaries are often called the “nurseries of the sea”.
-Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea.
Abiotic factors
In an estuarine ecosystem, these factors are light, oxygen, water, nutrients, temperature, salinity, and space. So just divide these into three.
Biotic factors
These include plants and animals such as shrimp, fish, and oysters
Answer:
Cytokinesis
Explanation:
The process of cell division involves the division of the cytoplasm and the nuclear material called genetic material. The process of nuclear division is known as the karyokinesis whereas the division of the cytoplasm is known as the cytokinesis.
The division of the cytoplasm takes place only after the genetic material is divided and the division of the cytoplasm is the final step of the cell division.
Thus, cytokinesis is the correct answer.
