they release methane gas and co2
There are various substances that animals release to the environment. Carbon dioxide is one of substances which is then taken in by plants for purposes of photosynthesis.
Nuclear power plants release the most radioactivity into the environment compared to other types of power plants. However, modern nuclear plants are designed with multiple layers of protection to prevent the release of radioactivity. When operated properly and following safety protocols, nuclear plants pose minimal risk to the environment.
If plants do not adapt, they do not survive in that particular environment.
Nonvascular plants reproduce through spores. They typically need a damp or moist environment to release their spores and for the spores to germinate and grow into new plants. This environment provides the necessary conditions for spore dispersal and establishment of the new plant generation.

The role that plants trees have within their environment is to enable them absorb carbon dioxide during photosynthesis and release oxygen, also act as wind breakers and also act as home of other animals such as birds.
During photosynthesis, plants release oxygen gas as a byproduct. This occurs when plants take in carbon dioxide from the environment and, through the process of photosynthesis, convert it into glucose and oxygen.
It depends on what aspect of the environment you are looking to improve. In any environment, it is the native species which are the best.
UMM... well, plants & animals take in carbon dioxide(oxygen) and then they release it for fresher air i guess.
ferns and plants.
