Answer:
Animals release carbon dioxide into the air, and plants take it in.
Explanation:
The existence of plants and animals on the planet is important in maintaining life. Animals release carbon dioxide as waste through the respiratory system. The carbon dioxide that is released is then taken in by plants, which they use to produce their own food through a process called photosynthesis. The by product of that process is oxygen which is released in the atmosphere and animals take it in.

Explanation:
The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
