The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers.
Explanation;
Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem. Ecosystem maintain themselves by cycling energy and nutrients.
The energy from sunlight is taken up by producers which use it to produce organic compounds through photosynthesis. The energy is then passed successively to the trophic levels, that is from the producers to the consumers ( primary, secondary, tertiary and quotienary consumers). During this transfer some energy is lost at each trophic level in form of heat.

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.
