With reference to food chains in ecosystems, consider the following statements:
1. A food chain illustrates the order in which a chain of organisms feed upon each other.
2. Food chains are found within the populations of a species.
3. A food chain illustrates the numbers of each organism which are eaten by others.
Which of the statements given above is/are correct?
The question asks us to evaluate three statements about food chains in ecosystems. We need to determine which of these statements accurately describe a food chain.
Based on the analysis, only statement 1 is correct.

Consider the following pairs:
| National park | River flowing through the Park |
| 1.) Corbett National park | Ganga |
| 2) Kaziranga National park | Manas |
| 3) Silent Valley National Park | Kaveri |
Which of the above pairs is/are correctly matched?
The question asks to identify the correctly matched pairs between National Parks and the rivers flowing through them. We need to evaluate each pair individually based on geographical facts.
Corbett National Park is located in Uttarakhand, India. The main river flowing through Corbett National Park is the Ramganga River, a tributary of the Ganga. While the Ramganga eventually joins the Ganga, the Ganga itself does not flow directly through the core area of Corbett National Park.
Kaziranga National Park is located in Assam, India. The primary river flowing through Kaziranga National Park is the Brahmaputra River. The Manas River flows through Manas National Park, which is also in Assam but is a separate protected area located further west.
Silent Valley National Park is located in Kerala, India. The main river flowing through Silent Valley National Park is the Kunthipuzha River, which is a tributary of the Bharathappuzha River. The Kaveri River flows through Karnataka and Tamil Nadu, far from Silent Valley National Park.
Based on the evaluation of each pair, none of the given pairs are correctly matched.
D) None. As established in the step-by-step analysis, all three pairs are incorrectly matched.
consider the following organisms:
1. Agricus
2. Nostoc
3. Spirogyra
Which of the above is/are used as biofertilizer/biofertilizers?
The question asks to identify which of the given organisms are used as biofertilizers. We need to recall the characteristics and applications of each organism listed.

Based on this analysis, both the excretion of urea by animals and the death of vegetation are natural processes that add nitrogen to the soil.
Correct Option: C) 1 and 3 only
In which of the following States is lion-tailed macaque found in its natural habitat?

1, 3 and 4 only
1, 2, 3 and 4
The question asks to identify the states where the lion-tailed macaque is found in its natural habitat. This requires knowledge of the geographical distribution of this specific primate species in India.
Correct Option: A) 1, 2 and 3 only
