Explanation:
During an algal bloom the species produce a toxic chemical substance which is harmful to animals that feed on the algae that causes a tint in the water because of the photosynthetic pigments is known as a red tide a red tide may or may not be harmful . Nonetheless algal bloom can produce both beneficial and harmful cycles.
It is beneficial because it can provide organic compounds needed by higher organisms, for this reason productivity increases because there's more algae in the water which means that more carbon dioxide is used from the atmosphere and that more oxygen is being released into the atmosphere which is needed and necessary for many living things
Answer:
B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.
Explanation:
According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.
Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.
Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.
The correct option is B.
Answer:
