A. Biologists studied the effects of forest fragmentation by calculating the difference between the amount of plant biomass in the edges of forest fragments and the interiors of unfragmented forest.1. True2. falseB. Which size forest fragment would be most affected by habitat fragmentation over a given period of time?1. 100 hectares. 2. 1000 hectares. 3. 10 hectares. 4. 1 hectare. C. Which of the following statements about the effects of forest fragmentation on plant biomass and species diversity is true? 1. The loss of plant biomass correlates mostly with the death of understory plants. 2. The loss of plant biomass has a domino effect on other species that live in the forest fragment. 3. Large forest fragments (>1000 hectares) are not affected by edge effects and their species diversity is expected to be stable over a long period of time. 4. Small forest fragments lose their species diversity at the same rate as large forest fragments.

1. True

2. Option 4

3. Option 2

Explanation:

1.Forest interiors are region that show no sign of detectable edge influence and their condition is determined by using samples from un-fragmented forest from which the influenced forest edges are removed. Hence, the given statement is true

2.The smaller patch size of a place or landscape has more fragmentation issues. Hence, Option 4 is correct

3.Option 2

The initial extinction cascades that arises among the plant species first is then also  

affect other species such as animal in a given habitat. This effect is known as domino effect. In forest fragmentation, plant biomass is lost and the species dependent on this biomass is also adversely affected.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
