Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody
Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

  1. Sympatric
  2. Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.  

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.

Corals obtain energy from tiny photosynthetic algae, called zooxanthellae, which live inside the coral's tissue. how do you thin
olga_2 [115]
<span>Cloudy and muddy water will interfere with the penetration of light to particular depth in water where coral are found. The algae in the symbiotic relationship with the sponges will be unable to photosynthesize. This way, the sponges will lose the algae and become ‘bleached’. </span>
