Correct Answer
A. BiomassExplanation
Biomass refers to the total weight of all living organisms in an ecosystem. It includes plants, animals, and microorganisms. The biomass increases as a result of net production, which is the difference between the energy gained through photosynthesis and the energy lost through respiration. This means that when the net primary productivity is positive, more energy is being produced through photosynthesis than is being consumed through respiration, leading to an increase in biomass. Therefore, biomass is a measure of the total amount of living matter in an ecosystem.Rate this question:

A. SymbiosisExplanation
Symbiosis is the correct answer because it is a term used to describe any close relationship between two species. Symbiotic relationships can be mutualistic, where both species benefit, or they can be antagonistic, where one species benefits at the expense of the other. Co-evolution is a process that occurs in symbiotic relationships where two species evolve in response to each other over time. Therefore, symbiosis encompasses all types of close relationships between species.Rate this question:

Co-evolution
- D.
Antagonistic Co-evolution
Correct Answer
D. Antagonistic Co-evolutionExplanation
Antagonistic co-evolution refers to a relationship between species where they engage in a constant cycle of attack and defense mechanisms. This can lead to an arms race, where each species evolves traits to outcompete the other. In this scenario, chemical and mechanical methods are used by the species to defend against and attack each other. This type of co-evolution is often seen in predator-prey relationships or in interactions between parasites and their hosts.Rate this question:
