Increase in toxic concentration from one trophic level to another trophic level is called:
1 ecological succession
2 biomagnification
3 bio indicator
4 cytological effect
Explanation:
Increase in toxic concentration from the one trophic level to another trophic level is called biomagnifications. It is also known as bio-amplification. This occur when a certain chemical or toxins enter into the food chain through the environment. After that this toxin substances goes from one trophic level to another and increases in concentration. At the end it results in severe heath problem.

A lake with nutrients is called
1 Trophic
2 Euphoric
3 Oligotrophic
4 Eutrophic
Explanation:
The process of nutrient accumulation and enrichment of lakes is called eutrophication. A eutrophic lake is typically shallow with a soft and mucky bottom. Rooted plant growth is abundant along the shore and out into the lake, and algal bloom are not unusual. water clarity is not good and the water often has a tea color. If deep enough to thermally stratify, the bottom waters are devoid of oxygen.

If decomposers are removed what will happen to the ecosystem?
1 Energy cycle is stopped
2 Mineral cycle is stopped
3 Consumers cannot absorb solar energy
4 Rate of decompostion of mineral increases
Explanation:
If decomposers are removed, then the mineral cycle is stopped in the ecosystem. Decomposes are degrade the organic remains and converted it into minerals. In the absence of decomposes, organic remains will not be converted to minerals. Hence, it affected the mineral cycle.

The rate of decomposition is faster in the ecosystem due to following factors EXCEPT :
1 Detritus richer in lignin and chitin
2 Detritus rich in sugars
3 Warm and moist environment
4 Presence of aerobic soil microbes
Explanation:
The rate of decomposition is faster in the ecosystem if detritus is which in nitrogen and water soluble substances like sugars. The rate of decomposition is slow if it contains lignin, chitin, tannin and cellulose.
