Answer:
Explanation:
Pollution: The farming of marine fish, crustaceans and even bivalves produces waste in the form of fecal matter and unused feed. These largely nitrogen-based wastes can cause oxygen depletion in coastal environments and a net loss of marine productivity in certain coastal areas.
Answer:
The correct answer is option - C. They replaced carbon dioxide with oxygen in the atmosphere.
Explanation:
Cyanobacteria or Blue-green algae is a group of bacteria that is making its own food using water and carbon dioxide in the presence of sunlight, the process of photosynthesis
These organisms release oxygen as a byproduct of photosynthesis in the atmosphere. Through this process, these organisms replaced carbon dioxide with oxygen in the atmosphere in the early earth.
Thus, the correct answer is option C. They replaced carbon dioxide with oxygen in the atmosphere.
Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D
<h3>What is carrying capacity of a habitat?</h3>
The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.
The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.
Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.
In conclusion, the competition between the species of snakes is responsible for the decline in Species A.
