Organisms that cannot be seen by the naked eye. Need a tool to see them. e.g. magnifying glass or microscope
Always producers are the ones which produce their own food or act themselves as producers so they may be grass or plants while secondary consumers are the ones who feed on em.
There are a lot fewer secondary consumers than there are producers.
Answer:
They can breed and produce offspring that can breed.
Explanation:
The options you were given are the following:
- They can breed and produce offspring that can breed.
- They are members of the same community.
- They live in the same ecosystem, community, and biome.
- They have similar physical characteristics.
A species can be defined as a group of similar organisms that can reproduce and produce offspring that can produce as well. This is why the first option is the correct one.
In ecology, the term <em>community </em>refers to a group of populations of two or more different species that inhabit the same area. More than one species can be found in a biome and ecosystem as well, which is why the second and third options are incorrect.
Some organisms can look very similar but belong to different species. This is why the fourth option is not correct, either.
Answer:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic, faster than any known change in ocean chemistry in the last 50 million years.
