Which of the following is non-biodegradable ?
“Nitrous oxide is a green house gas” the above statement is-
Like other greenhouse gases, nitrous oxide absorbs radiation and traps heat in the atmosphere, where it can live for an average of 114 years, according to the EPA.
Find the incorrect statement-
Which of the following is not a terrestrial ecosystem
Which of the following constitute a food chain ?
Which of the following constitutes the forth trophic level ?
“Flow of energy is unidirectional”. It means that-
The maximum concentration of chemicals get accumulated in
DDT, a pesticide is-
Green house gases are-
Which of the following is biodegradable-
Montreal protocol became effective in-
Ozone depletion has resulted in-
Micro-organisms belongs to the group of-
Function of an ecosystem involves-
The driving force of an ecosystem is-
A food chain always starts with-
According to 10%10% law, the energy available to each successive level is _________ of previous level
The formula of Ozone is _______
The decomposers in an ecosystem-
In due given food chain, suppose the amount of energy available at third trophic level is 50 KJ, what will be the energy available at due producer level ?
Only 10% of the energy present is given to the consumer at the next level, of the total energy the level/animal has.
Therefore, if 4th Level = 5kJ
3rd Level = 50kJ
2nd Level = 500kJ
Producer = 5,000kJ
In the following groups of materials, which group contains only non biodegradable items.
An example of man-made ecosystem is -
Examples of man-made ecosystems are orchards, home aquarium, zoo, botanical gardens and park. These ecosystems are sustained by human interventions. Aquarium and zoo ecosystem, for example, cannot survive without the care of humans. Man-made ecosystems are created for specific purposes.
A food chain consist of
A food chain is a series of plants/animals which are interrelated in the form of an organism being eaten as food by the other. A food chain consists of producers and consumers. In the given food chain, plants are producers. The animals eating plants are called primary consumers and animals eating primary consumers are called secondary consumers.
Thus, the correct answer is 'Producers and consumers.'
The process of eating and being eaten is called-
The food chain is a sequence of populations or organisms through which food and energy are passed on an ecosystem with the members of each trophic levels. A food chain shows who is eating whom. Here, organisms of higher trophic level derive its nutrients from organisms of a lower trophic level.
