Answer:i cant tell you the answer dont want to give you wrong
Explanation:
The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
X is the dominant gene, and x is the recessive gene.

Introducing different kinds of crops to eliminate the cause of the fungal disease is the best solution that scientists have found to solve this. They have set-up seed vaults that store different kinds of seeds to help ensure the continuity of the types of crops that have been planted for the consumption of many.
see plants are also living beings, they also need oxygen for respiration. There would be less carbon dioxide available for plants for photosynthesis. Atmosphere will be clean, less polluted, clean water. No fighting, peaceful, cool environment
