Yes they are alive in numbers today and they are known as one of the most top shark killers there are, other than the great white shark and killer whales. *there is a pic below of the shark, I take no credit for it, I just found it off google.
Answer:
Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species
Please find the explanation below
Explanation:
In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.
A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.
Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.
Carcinogenesis or carcinogens cause cancer in the environment.
Answer: Disinfectant is a chemical formulation which may include biological components used to reduce the population of a microbe from a living or dead surface.
Explanation:
The plant tissue is treated with a disinfectant before culturing it and growing new plants. This is done to remove dirt, dust, foreign particles like pollen, microbes from the plant tissue surface or from plant part. This help in growth of disease free and contamination free plants. The culture can be utilized for different cycles of plant growth as it remains free from any kind of contamination.
