ECOSYSTEM ( EVS )

What distinguishes an Aquatic Ecosystem from a Terrestrial Ecosystem?

Aquatic ecosystems are water-based environments, while terrestrial ecosystems are land-based environments.

What are Natural Ecosystems?

Natural ecosystems exist without significant human intervention and are characterized by self-regulating mechanisms.

Give an example of an Artificial Ecosystem.

Examples of artificial ecosystems include agricultural fields and urban parks.

What is a Producer in an ecosystem?

Producers are organisms that synthesize their own food, mainly through photosynthesis.

What role do Decomposers play in an ecosystem?

Decomposers break down dead organic matter and recycle nutrients back into the ecosystem.

What are Abiotic components?

Abiotic components are non-living chemical and physical parts of the environment that influence living organisms.

What is the difference between a Food Chain and a Food Web?

A food chain is a linear sequence of energy transfer, while a food web is a complex network of interconnected food chains.

Describe the Carbon Cycle.

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere.

What does the Nitrogen Cycle involve?

The nitrogen cycle involves the conversion of nitrogen into various chemical forms through processes like nitrogen fixation and denitrification.

What causes Ozone Depletion?

Ozone depletion is primarily caused by the release of human-made chemicals like chlorofluorocarbons (CFCs) that break down ozone molecules.

What drives Global Warming?

Global warming is primarily driven by the burning of fossil fuels, which increases greenhouse gas levels in the atmosphere.

What is the Phosphorus Cycle mainly characterized by?

The phosphorus cycle is characterized by the movement of phosphorus without a significant atmospheric gaseous phase; it primarily involves sedimentary processes.

What is the significance of Decomposers in ecosystems?

Decomposers are crucial for recycling nutrients and maintaining soil fertility.

Define an Ecosystem's structure in terms of components.

An ecosystem's structure consists of biotic (living) and abiotic (non-living) components that interact with each other.
