Answer:
E. Both the assertion and the reason are incorrect.
Explanation:
Coral reefs are found in the tropical water which is poor in nutrients. The species of coral that form the reefs have symbiotic zooxanthellae in their tissues that can carry out the process of photosynthesis. The coral reefs obtain their food from their symbiont and hence, can survive in the water that lacks enough supply of nutrients.
Coral reefs also use their stinging tentacles and capture the small animals to feed on them. However, the food derived from symbiont zooxanthellae is the major source of nutrients for them.
Answer;
D. The immigration of the population is greater than the emigration.
Explanation;
A population consists of all the organisms of a given species that live in a particular area.
Populations change based on the births, deaths, immigrations, and emigrations that occur within the group. These additions and subtractions all affect population size, but do so in different ways.
Immigration is the migration of individuals into a population. Emigration, which is the migration of individuals out of a population, decreases the size of the given population.
B.) Adding a catalyst can increase the rate of reaction
