I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.
Grassland terrestrial biomes are both dependent upon periodic severe drought and/or fire.
Terrestrial biomes are ecosystems that can be found anywhere on earth that has a similar climate pattern and are not necessarily close to one another. Tropical forests are an illustration of a terrestrial ecosystem. Forests, grasslands, deserts, and tundra are some of the different biome types found in the terrestrial environment. There are eight main terrestrial biomes: temperate grasslands, temperate forests, boreal forests, Arctic tundra, and tropical rainforests, savannas, subtropical deserts, and chaparral.
The grassland biome consists of terrestrial areas where grasses predominate and there aren't many big trees or bushes. Temperate grasslands, tropical grasslands (sometimes called savannas), and steppe grasslands are the three main types of grasslands.

Food web only contains interactions between trophic levels while an interaction web shows both trophic and non-trophic interactions.
Answer:
If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.
Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.
