Biology
Of the four major causes for the loss of biodiversity (alien species invasion, habitat loss, fragmentation, over-exploitation, and co-extinctions which according to you is the major cause for the loss of biodiversity? Give reasons in support.
Mention the product and its use produced by each of the microbes listed below:
(i) Streptococcus
(ii) Lactobacillus
(iii) Saccharomyces cerevisiae
- gradual and predictable change in species composition occurs in a given area
- the establishment of new biotic community is very fast in its primary phase
- the number and types of animals remain constant
- the changes leads to the community that is near eqillibrium with the environment and is called pioneer community
an association of individuals of different species living in the same habitat and having functional interaction is:
- ecological niche
- biotic community
- ecosystem
- population

- ectoparasitism
- symbiosis
- commensalism
- ammensalism
A biologist studied the population of rat in barn he found that the average natality was 250, average mortality 240, immigration 20 and emigration 30 the net increase in population is

- 15
- 5
- zero
