Answer: In terrestrial ecosystems the presence of vegetation in floodplains and watersheds can reduce the occurrence and severity of flooding by slowing water flows, enhancing percolation and storage, and allowing gradual release of water, thereby maintaining base flows and reducing peak flows.
Explanation:
Stem cells can differentiate into any type of cell so they can be used to produce/repair nerve tissues. Advantage of using embryonic stem cells is that they are easier to extract than adult stem cells.
Evolution means that populations of organisms change over time.
Explanation:
Evolution refers to the phenomena by which a population develops new traits and becomes more and more fit to survive in a given environment.
Evolution can be studied in two different ways- as a pattern of evolutionary changes and as a process of evolution.
Study of Evolution help us to understand the history of life.
Evidences of evolution support the view that species evolved from common ancestors rather than created separately..
These evidences are contributions of various fields of biology and geology.
Answer:
Interspecific competition is a competition between two species for obtaining the same resource. For example, lion and leopards are cat species but feed on the same prey so they compete for the same resource.
Interspecific competition may lead to resource partitioning through the change in their niche by one species to avoid interspecific competition.
For example, <em>Anolis evermanni</em> and <em>Anolis gundlachi</em> are two species of lizards live on Puerto Rico island and compete for the same resource i.e., insects so to avoid interspecific competition they did the resource partitioning.
Anolis gundlachi feeds near the ground and Anolis evermanni prey on upper branches of trees so in this way they avoid competetion.
