Answer:
A bottom-up system concentrates attention on how resources (space and nutrients) influence higher trophic forms , whereas a top-down system focuses on interactions at top level consumers (predators) and their prey influence on lower trophic forms.
Explanation:

D is the correct answer since all others are highly unlikely.
If the prey population is thriving, then the predator population will as well- or at least, until they eat out that population, then the prey and the predators will be at a decline. It's a balance.
Answer:
Cortical Bone and Cancellous Bone
Explanation:
They're both bone tissue.
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
- Dimorphism is the condition of those<em> species</em> of animals or plants that exhibit two anatomical aspects or two different forms.
- When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.
- Continuously variable traits are those that show a continuous distribution of phenotypes.
Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.
