Summary Introduction
To review:
The given blank space in the statement, “three levels of biodiversity are___________, ___________, and ___________. If the population of a species becomes too small, it is likely to have lost much of its _____________ diversity.”
Introduction:
The term ‘biodiversity’ refers to the number of different varieties of species living on the earth. It includes plants, animals, microorganisms, as well as the entire ecosystem such as forests, national park, tiger reserve, bird sanctuary, and deserts. It is necessary to conserve the earth’s natural diversity because it is the basis for maintenance of the fauna and flora of ecosystem.

The major threats to biodiversity include _______ ,_______ ,_______ ,_______,and_______ . For most endangered species,________is probably the major threat.
A(n) community is a group of species that occupy the same area. When studying the diversity of a
group of species, ecologists use two measures: One is a count of the total number of species in the
area, which is called
The other is a measure of how common the species are, compared to
each other, which is called
Imagine a community of organisms in a forest is affected by a chemical spill that
leads to a fire. The fire is contained and burns out and the chemical spill is cleaned
up. Monitoring of the plant community following this disturbance researchers
noticed that after the spill and fire there was a sharp drop in species diversity,
abundance, and richness. Over the next 5 years the area was monitored. The
community's diversity, abundance, and richness all increased slightly during the first
year however after the first year only the abundance went up during the following 4
years with no changes in any other area. Which of the following models explains
these patterns?
Restructured
Gradual recovery
Hangover effect
Eliminated
