This should be the omitted answer choices to the question:

a. It decreases the carbon dioxide in the water, creating a toxic environment.

b. It decreases oxygen in the water, creating a toxic environment.

c.It increases the carbon dioxide in the water, stimulating plant growth.

d. It increases the oxygen in the water, stimulating plankton growth.

Answer:

b. It decreases oxygen in the water, creating a toxic environment.

Explanation:

A rapid increase in algae populations in a marine ecosystem as a result of high levels of nitrogenous compound would result in increased level of dead organic matters from algae. This would mean more food for bacteria that are present in the marine ecosystem, which would further lead to the rapid increase in the population of bacteria in the marine ecosystem. The presence of more dead organic matters would favor the surge in the population of bacteria. Bacteria require oxygen to survive. As the population of bacteria increases rapidly, the level of dissolved oxygen in the water would drop as bacteria would make use of most of the dissolved oxygen available, thereby disrupting the ecosystem of the marine habitat.

The survival of most aquatic organisms is dependent on the level of dissolved oxygen available as most aquatic fish and insects would die as the level drops. Some species of algae produce toxins which also harmful to aquatic life.

Alga bloom would affect a marine ecosystem by reducing the level of dissolved oxygen needed by other aquatic organisms to survive, and also leads to high level of production toxins detrimental to other aquatic organisms.

Ahat [919]

Steroid estrogens, such as estrone, estradiol, and estriol, are dangerous to soil, plants, water resources, and humans.

<h3>What is "Assault on the Male"?</h3>

This Emmy Award-winning documentary investigates that terrifying possibility. Scientists use sophisticated investigative techniques to track the environmental impact of estrogenic substances.

Small disruptions in the natural order, then the larger consequences: drastically altered ecosystems and disturbance of essential life processes, resulting in decreased male reproduction.

Thus, this way it has shown the effects of environmental estrogens on wildlife and humans.

I need these answered in 1-2 small sentences.
schepotkina [342]

Answer:

Explanation:

1Organisms are classified into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.

2 The purpose of a domain is to research their species, their animal group, and their resources. This will help you identify them with other familise to compare and contrast.

3 The three domains are the Archaea, the Bacteria, and the Eukarya. These domains makes up the animal kingdom levels.

4Organisms are classified into domains and kingdoms based on their cell .type. Their ability to make food, and the number of cells in their bodies are also reasons.

5  Each name has two parts, the genus and the species. The binomial system is important because it allows scientists to accurately identify individual species.
