The correct option is this: PIONEER ORGANISMS MOVE INTO NEW COMMUNITIES FIRST.

Ecological succession refers to the process of change that occur to the species in a given community over a period of time. Succession is caused by change in the environment and its effects on the living organisms that are living there. There are two basic type of ecological succession, these are primary and secondary ecological succession.

Primary ecological succession typically occur in an environment that is devoid of any form of vegetation or life form; it is usually a bare land that lack soils that are needed for plants' growth. The first set of plant that grow in this kind of environment are called pioneer species. Such plant usually have ability to survive in harsh environment. Example of such plant is ferns. Primary succession is very slow and can take hundreds of years.

Secondary succession usually occur as a result of an event which reduce an established ecosystem into a smaller population. The event could be a forest fire, flooding, etc. Secondary succession takes place in an environment in which some living organisms are still existing. The process is fast compared to primary succession.

How does the lack of insulin prevent cells from using glucose?

tekilochka [14]

Answer:

the pancreas secretes insulin, which directs the muscle and fat cells to take in glucose. Cells obtain energy from glucose or convert it to fat for long-term storage. Like a key fits into a lock, insulin binds to receptors on the cell's surface, causing GLUT4 molecules to come to the cell's surface.

What is a likely advantage of having a multicellular body that consists of fine filaments (hyphae)?

Naddika [18.5K]

Hyphae are a filamentous vegetative structure of some fungi and a large network of hyphae form a mycelium (vegetative body). Mycelium is actually mass of branched, tubular hyphae. Because of its structure, hyphae enable the fungi structural strength (it is composed of at least one cell encapsulated by a protective cell wall usually made of chitin). The combination of branching hyphae with their radial/diffuse growth is a huge advantage for mycelium that can explore and exploit a large area. Also, hyphae and their organisation (diffuse or radial growth) have a role in the absorptive nutrition of the fungi. For example, parasitic fungi have specialized hyphae with tips, haustoria, which penetrate the host organisms or symbiotic fungi that have specialized hyphae, arbuscules, which can be found in the roots of vascular plants.
