Answer:
The answer is C)
Explanation:
The predators were unable to keep the population of the mussels down. The mussels took more area of the rock. Other species that needed space did not return to the tidal pool. Otters can also be keystone species as they eat urchins. By doing so, they prevent the sea urchins form eating all the kelp plants and removing the entire habitat for many other species. The Keystone Species theory shows that this impact of few predators, that made up a minor amount of the total species, could have such a high impact on the ecosystem.
Answer:
The invasive s p e c i e s tend to diminish the populations of native s p e c i e s because they outcompete them, and also manage to disturb the ecosystem.
Explanation:
The invasive species can or cannot be dangerous for the native biodiversity, but unfortunately, it is the second one that is much more common. The reasons as to why the invasive species tend to threaten the biodiversity are that they often don't have a native predator that will control their numbers, outcompete the native species for resources, and the native species don't have defense mechanisms against them. These factors result in havoc in the ecosystem in a relatively short period, with the potential to totally destroy it and changed it.
There are thousands of examples of invasive species around the world, some much more obvious than others. The Burmese pythons in Florida for example, have started to overtake the a p e x predator niche from the alligators by directly attacking them. On the other side of the world, in Australia, the cats and rabbits have contributed to leading hundreds of native species on the verge of extinction, and if there hasn't been human intervention there is a very high chance that a lot of native species would have been already extinct.
A since they must have evolved for a common ancestor or they would have different bone structure
Belize's population has adapted to use the tropical rainforest and the waters in order to survive in the harsh environment.
Explanation:
Belize is a small country that is cover with dense, tropical rainforest. It comes out on the Caribbean Sea, and it is a country that is abundant with rivers and streams. The tropical rainforest is a very tough place for living, especially if the lifestyle of the population is not of primitive type, so the people are almost exclusively settled along the coastline.
The tropical rainforest is used as a natural, free, high producing garden of fruits, but also lot of plants used for medicine. The people also tend to hunt a lot, as there is an abundance of animals. The primary source of resources though are the rivers and the sea, where the majority of the population is involved in fishing and gathering sea plants.
<span>Sole proprietorships are more numerous, but corporations sell more goods. While any single individual may declare his business a corporation, generally speaking, most large corporations have more money, resources, and connections than the average sole proprietorship. A large corporation may sell their goods across state borders or internationally, for example.</span>
