2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?

3. how might the building of the hotel affect the population of the new species?

Answers

Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.

Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.

The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

What are the two ways that harmful algal blooms can negatively impact an ecosystem? (Site 1).

Answers

Answer:

SEE EXPLANATION FOR ANSWER

Explanation:

Eutrophication: An abundance of cyanobacteria (an algal bloom) is caused by an excess amount of nutrients in the water (phosphorus and/or nitrogen) which depletes the water of oxygen which is vital for plant an animal life. Oxygen is crucial for the survival of an organism, so when there is a lack of oxygen, the results can be fatal. That is why when there are reports of algal blooms, there are almost always mentions of an abundance of dead fish, birds, and other water dwelling organisms (these organisms live in the water, drink from it or use it as breeding grounds etc,) Not only that, but algal blooms produce toxins that can make animals and humans fall ill.

Dead zones: As stated previously, harmful algal blooms deprive the water of oxygen.This can lead to the extreme and create dead zones. Dead zones are zones in an aquatic body where the oxygen levels are not sufficient enough to support aquatic life. Hence why there is no life in dead zones because all of the fish either die, or leave.

Both affect the population of native species and the overall wellbeing of the bodies of water.
