A. Biologists studied the effects of forest fragmentation by calculating the difference between the amount of plant biomass in t
he 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. 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.
During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. look up in ur book meiosis which will explain more
The energy in coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests. After some time dirt and water started to stack compressing it to rock or also known as coal.
Explanation:The energy needed by living things comes from the sun. Every ecosystem depends on green plants to trap the energy in sunlight and change it into chemical energy. The process by which green plants convert the sun's energy is called photosynthesis.
Foreign invaders have proteins called antigen, which antibodies lock onto to neutralize. The foreign proteins are different from proteins in our own body, so the immune system can recognize them and finally eliminate them.
