Answer: c. volcano

An ecological succession is a gradual change in the biological community due to changes in the non-living or abiotic factors of the ecosystem and with respect to time until the ecosystem attains stability. Primary succession occurs in region which is not previously inhabitat by any floral or faunal species. It occurs specifically in barren and lifeless landforms. This includes regions where soil is incapable for plant growth.  Hot lava released after volcanic eruption will make the soil unsuitable for plant growth also rocks found in these regions are compact. Therefore, pioneer or primitive species act on such rocks and soil like lichen and produces acids which remove the compaction from these soils and make them suitable for growth of plants in that region.

GenaCL600 [577]

Answer:

Herbivorous animals are unable to feed and end up migrating to other regions in search of food.

Explanation:

The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.

List five introduced species that present a serious threat to their new communities. explain the damage done by each introduced
Delicious77 [7]
Cat (Australia); lots of cats became feral and they reproduce very fast. They became the apex predator and the native species have no defense system for them, so the cats brought tens of species on the verge of extinction (mainly placental mammals).
Fox (Australia); became an apex predator in the lack of competition, and damages the populations of native small placental mammals. 
Hair (Australia); reproduces much quicker than the native species of mammals, increased significantly in numbers, and out competes the native species for the food sources.
African bee (the Americas); much more aggressive and stronger than the native bees and systematically kills their populations.
Grey squirrel (Britain); reproduces quicker than the red squirrel, is bigger, and out competes for food, brought it on the verge of extinction.

e-lub [12.9K]
The sensory receptors located on a frog's head assist it in the water through protection and flotation. The receptors hold the frogs head above the water, and the frog uses this as an advantage to see if there is any predators or prey around to help it survive. Hope this helps!
