1 Eagle and snakes
2 Insects and cattle
3 Snakes and Frogs
4 Water insects
Explanation:
The consumers in an ecosystem are heterotrophs mostly that depend for food on other organisms. The consumers are known to be herbivores. Insects and cattle is belong to the primary consumer because feed on plant, plant is producer.

Which one of the following is a characteristic features of cropland ecosystem
1 Ecological succession
2 Absence of soil organisms
3 Least genetic diversity
4 Absence of weeds
Explanation:
Cropland ecosystem posses least genetic diversity. Man has done his best to change the croplands to get full value from them. This includes the addition of fertilizers to the soil the application of pest control agents, good irrigation methods. The least genetic diversity is a characteristics feature of cropland ecosystem. - A crop land ecosystem will have a major crop cultivated in a given area. It shows that the diversity in that particular area will be least. Where as it is the opposite when forest ecosystem is considered.

Study the four statements (a-d) given below and select the two correct ones out of them -
1 $\mathrm{A}$ and $\mathrm{D}$
2 A and B
3 B and C
4 C and D
Explanation:
Carnivores (lion) and herbivores (deer) both are consumers, occupying different trophic levels in a food chain. - Predation is a relationship in which member of one species consume members of another species (the prey). - A predator prey relationship keeps the populations of both species in balance. Predators (e.g. pisaster) control prey population and reduces competition among prey species. - Nicotine and strychnine are secondary metabolites that usually are photochemicals which act as antimicrobial attractants or repellents or as deterrents against herbivores but does not cause any arm to their metabolism.

Which one of the following is most appropriately defined
1 Parasite is an organism which always lives inside the body of other organism and may kill it.
2 Host is an organism which provides food to another organism
3 Amensalism is a relationship in which one species is benefited where as the other is unaffected.
4 Predator is an organism that catches and kills other organism for food
Explanation:
Predation is an interaction between members of two species in which members of one species capture, kill and eat up members of other species 'Host' is a term which is specifically related to parasitism. - Amensalism is an interspecies interaction in which one species is harmed where as the other one is unaffected. - Parasitic organism can live both over the surface of their host or inside their body.
