I would say D...just because of the greenhouse effect
Answer:
The correct answer is: (A).
Explanation:
- In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
- Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
- However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
- Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
- However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
- This allows more nutrient rich sea water to percolate into the ice and reach the algae.
- The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
- Hence, more algae are produced under such a situation.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
As food becomes scarce, monkeys within the same tribe can fight for food resources. This behaviour describes intraspecific competition.
<h3>What is intraspecific interactions?</h3>
Intraspecific competition is a competition between someone from the same species . Theimpact of competition on each individual within the species relies on the type of competition that takes place.
'The competition' may be inactive or active and may result in ovarious outcomes.
Thus, This behaviour describes intraspecific competition.
