Life form that should eat or burn-through different creatures to get energy and supplements. Investigation of how living creatures connect with one another and with their current circumstance. The entirety of the living things and non-living things cooperating in a similar region. Natural or ecological territory where a specific animal categories reside.
Answer: Option A.
It is called specie- area relationship.
Explanation:
Specie- area relationship in ecology describe the relationship between the area or habitat and the total number of species present in the area. It is also called species-area curve.
A larger area will contain a larger number of species.
A lot of factors determine the slope and elevation of specie-area relationship and they are, immigration and extinction rate, predator- prey dynamics, rate of disturbances between large and small area e.t.c.
Answer:
a. The original spraying has caused a permanent mutation, giving the insects genetic resistance to the spray.
Explanation:
This is a practical evidences of mutation and variation, as mechanisms of evolution.
The insecticide is the selective pressure. As a results of continuous spray, the parents of the present mosquitoes must have acquired certain characteristics or traits by gene mutation which makes them resistant to the selective pressure (insecticides), and therefore survive the spray in the past.
Therefore when these resistant parents mated, with high reproductive success (leading to large gene pool of these traits,); variation in the genetic composition increases as the resistant gene is passed from generations to generations in the population. Therefore, the population of present day mosquito with genetic resistance to insecticides increases.They are therefore naturally selected, and able to survive as the present day mosquitoes with high resistance to insecticides.
<span>Moose are generally docile towards humans, but may become more aggressive during the mating season of September through October.The name "moose" comes from the Native American word "Moswa," which translates to "twig eater."On average, moose live 10 to 15 years in the wild. Moose are considered fully mature at 4 to 5 years of age.Moose are remarkably agile for their size, capable of running at speeds of up to 35 miles per hour.Moose are capable of swimming up to 10 miles without stopping.Moose are unlike many other deer species in that they are mostly solitary animals. However, strong bonds exist between mothers and calves.The moose population in North America is estimated to be fewer than 1.5 million, with 1 million in Canada alone. Up to 200,000 are estimated to live in Alaska.Moose are herbivores, and eat a large amount of terrestrial vegetation, but they also must need to consume a good amount of aquatic plants which provide moose with sodium.Moose must consume 9770 calories per day to maintain their body weight.A moose will eat up to 70.5 pounds of food a day.If a bull moose is castrated, he will shed his current set of antlers and grow new, deformed and misshapen antlers which will never be shed again. These antlers are often called "devil's antlers" and are the source of several Native American myths. In rare cases, cow moose may grow antlers due to a hormone imbalance.Because of their heavy bodies suspended by spindly legs, moose are especially dangerous when hit by passenger cars. If you are driving in an area where moose are plentiful, use caution and pay attention at all times.<span>Moose antlers may weigh up to 70 pounds, and measure 6 feet across.</span></span>
