Answer:
Explanation:
The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.
<h3>What is biomass?</h3>
- Renewable organic material obtained from plant and animal sources if referred to as biomass.
- Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
- Primary productivity is measured as biomass produced per unit area over a give time period
- It is usually expressed either in weight or energy.
- There are two ways to express primary productivity:
a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.
b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.

scientists can test differences of the area with pigmentation by observing which is lighter and which is darker however they use microscope to look the difference of the pigmentation over the cells.
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.
