The coral provides the algae with a protected safe environment (a home) and compounds they need for photosynthesis. The algae in return, produce oxygen and help the coral to remove wastes. Most importantly, zooxanthellae supply the coral with glucose, glycerol, and amino acids, which are the products of photosynthesis.
Cover crops suppress weeds and reduce damage by diseases, insects and nematodes. Many cover crops effectively suppress weeds as: a smother crop that outcompetes weeds for water and nutrients. Residue or growing leaf canopy that blocks light, alters the frequency of light waves and changes soil surface temperature.

Answer:
Same phenotype but different genotype is possible due to presence of dominant allele
Explanation:
A person can have a dominant allele on both the homologous chromosomes while another person may have single dominant allele and a corresponding recessive allele.
The answer is invasive species.
<span>Invasive species are species that are not native to the specific ecosystem, but they are capable of spreading widely through the ecosystem. This way they can threaten native species of the ecosystem or cause environmental harm.

<span>After being introduced into the
Hawaiian Islands, the cane toads greatly affect local ecosystem. In the new area, they
have a few natural predators and are able to spread. If they spread beyond
the area they are introduced, they become invasive species which can
overgrow native biotopes and are a great threat to the local biodiversity.
This could lead to the extinction of some native species.</span>
