Answer:
- Organism A is most likely a herbivore
- Organism B is most likey a carnivore
Explanation:
Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.
- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.
Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.
- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.
Answer:
Sexual selection
