The answer is B. a community <span>interaction.
Let's distinguish some terms:
A population is a group of organisms of the same species in an area. If there were a herd of only zebras, this would be a population interaction.
<em>A community is a group of organisms from different species in an area. </em></span><span><em>A herd of zebra eating grass includes groups of organisms from different species is an example of a community interaction.</em>
An ecosystem consists of all organisms (from different species) in an area and their physical environment.
A biome is a large area defined by abiotic factors.</span>
Answer:B. All of the above
Explanation: Fossil fuels do generate electricity. Example burning coal
Acid rain is cause by Sulfur dioxide. Sulfur dioxide is produced from powerplants.
When you burn Fossil fuels it increases the atmospheric Co2.
Answer:
<em>The correct options are D. dark-colored, small-sized snails and F. dark-colored, large-sized snails</em>
Explanation:
Evolutionary studies show that those organisms are able to survive and reproduce which are better adapted to live in an environment. Gradually, the organisms that are better adapted to live in an environment increase in number and those that are not better adapted will decrease in population.
As Avian snail kites feed on light- colored apple snails and Avian limpkins feed on medium- sized apple snails, this means that these species are not better as they can be easily captured by their predators.
The dark colored, small- sized snails and dark- colored, large- sized snails will be better adapted to live in the environment as they will not attract the predators. Hence, they will survive and reproduce.
