The given question is incomplete as it does not have the options which are:
A. commensalism
B. mutualism
C. parasitism
D. predator-prey
Answer:
B. mutualism
Explanation:
The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.
When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.
In the given question, the shrimp provide a safe habitat to the goby fish whereas goby fish protect the shrimps from the predators. Since both the species are benefitting each other therefore the species form a symbiotic relationship.
Thus, Option-B is the correct answer.
The most accepted theory regarding the make-up of living things is the cell theory.
It was proposed by German scientists Theodor Schwan, Mathias Schleiden and Rudolf Virchow.
It states that;
1. All living organisms are made of cells.
2. The cell is the basic unit of life.
3. Cells arise from pre-existing cells.
in addition the modern version of the cell theory states:
4. Energy flow occurs within cells
5. Heredity information (DNA) is passed from cell to cell.
6. All cells have the same basic chemical composition.
The answer is false.
The variability in marine salinity between habitats does impact the fish living there.
I hope this helps.
