You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Primary consumers are organisms that eat primary producers (such as plants). Pigeons that eat wheat are consuming plant material, making them primary consumers.

Who is primary consumer of biotic community?

Explanation

In a biotic community, primary consumers are organisms that directly consume producers (plants). These are typically herbivores or grazing animals. They play a crucial role in transferring energy from producers to higher trophic levels in the food chain.

which of the following option is correct for storage place phosphorus and nitrogen respectively ?

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Phosphorus is primarily stored in parental rock as phosphates, and nitrogen is mostly found in the environment, particularly in the atmosphere as nitrogen gas (N2). These elements are crucial for various biological processes and are cycled through ecosystems.

It is correct for ecosystem

Explanation

An ecosystem includes both biotic (living) components such as plants, animals, and microorganisms, and abiotic (non-living) components like soil, water, and air. The interaction between these components sustains the ecosystem.

Explanation

Decomposers play a crucial role in breaking down dead organic matter, which recycles nutrients back into the ecosystem. Without decomposers, the flow of nutrients would stop, which would disrupt the ecosystem's functional efficiency.

From which of the following detritus food chain will start ?

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

The detritus food chain begins with dead organic matter and is decomposed by microorganisms such as bacteria. Hence, the correct option is 'Bacteria'.

At Each trophic level, in which formenergyis lost ?

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Energy is lost at each trophic level primarily in the form of heat due to metabolic processes. As organisms consume food and convert it into energy, a significant portion is lost as heat. This concept is based on the second law of thermodynamics, which states that energy transfer is not 100% efficient and that some energy is always lost as heat.

Which Source of eutrophication is the modern source of phosphorus ?

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Modern sources of phosphorus that lead to eutrophication include detergents. Detergents often contain phosphates, which, when they enter water bodies through domestic wastewater, can result in the overgrowth of algae and subsequent eutrophication.

It helps in absorbtion of phosphorous ?

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Mycorrhizae are symbiotic associations between fungi and plant roots that enhance the absorption of phosphorus. The fungi extend the root system's reach, allowing plants to access phosphorus more efficiently from the soil.
