Answer:
The correct answer is B. exploitation
Explanation:
Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.
So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.
Answer:
e) Invertebrates lack a nervous system
Explanation:
One of the main characteristics of invertebrates is that they don't have a backbone. Backbones belong to the skeletal system. A totally different story is the nervous system which runs inside the backbone. Although the more complex nervous systems appear in vertebrates the simply fact of having eyes like crabs or insects implies having a nervous system that can control them.
Plants have the fewest similarities with the other two groups of organisms.
<h3>Plants vs animals</h3>
Plants generally comprise all living organisms that have chlorophyll and are able to manufacture their own foods by photosynthesis.
Animals, on the other hand, are living organisms that cannot manufacture their foods and are mobile. Animals are either vertebrates or invertebrates.
Plants qualify as living organisms because they are able to feed, excrete, reproduce, grow, respond to stimuli, die, and carry out other basic characteristics of living organisms.
