Red blood cells have no mitochondria and generate energy anaerobic. So, the answer would be B. You can easily eliminate A. and C. because they mention that blood cells have a mitochondria, but they don’t.
A long, wet season results in additional earthworms in a robin habitat.
Explanation:
A long, wet season resulting in additional earthworms in a robin habitat will not lead to competition in an ecosystem or area.
Competition between organisms is the struggle for limited resources in the environment that are beneficial to all lives.
- Competition is usually driven by shortages and lack of resources to make life better in the ecosystem.
- When resources becomes depleted and are in limited amount organisms will begin to strive among on another to develop advantages that would make them top out.
- A long, wet season resulting in the introduction of additional earthworms in a robin habitat is not an example of competition.
- The earthworms available is a limiting factor and this has been circumvented by the introduction of more earthworms during the prolonged wet season.
