Multiple choice commercial applications issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

Applied and basic aspects of environmental science require a solid foundation in

  1. Anthropogenic

  2. Natural Sciences

  3. Multi-disciplinary nature

  4. All of Above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Environmental science is an interdisciplinary field that relies on the principles of natural sciences (biology, chemistry, physics, geology) to understand environmental systems.

What does environment include?

  1. Biotic and abiotic factors

  2. Animals and Plants

  3. Microorganisms

  4. Non-living things
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The environment is defined as the sum of all living (biotic) and non-living (abiotic) components that surround and influence an organism. Options B, C, and D are subsets of these factors, making A the most comprehensive definition.

Function of an ecosystem means

  1. Rate of biological flow, nutrients and ecological regulations

  2. Temperature zone for stability

  3. Light emitting diodes

  4. Life cycle of species
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ecosystem function refers to the biological, geochemical, and physical processes that take place within an ecosystem. This includes the flow of energy and the cycling of nutrients.

Multiple choice evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

What is role of an acosystem?

  1. providing nutritional support to plants

  2. to generate life continuity, flourishing distinctive structure to all species

  3. helping animals to survive in an environment

  4. All of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An ecosystem functions to maintain life by cycling materials and providing structure, which ensures the continuity of various species. The other options are too narrow or incomplete.

Multiple choice evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

If ELR exceeds ALR, environmental lapse rate, would be considered as:

  1. ELR

  2. Lapse rate

  3. Super adiabatic

  4. Adiabatic lapse rate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When the Environmental Lapse Rate (ELR) is greater than the Adiabatic Lapse Rate (ALR), the atmosphere is considered unstable. This condition is specifically referred to as super-adiabatic.

In man subsidized powered ecosystem, power or energy input by man is, in form of

  1. Fertilizers and machines

  2. Tides and waves

  3. waves and currents

  4. Nuclear energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A man-subsidized ecosystem is one where human intervention provides additional energy to supplement natural processes. Fertilizers and machines are classic examples of such human-provided energy inputs.

Multiple choice evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

Ecosystem may be defined as 

  1. A localized association of several plants and animals

  2. Different communities of plants, animals and microbes together with thier physico-chemical environment

  3. Different communities of plants microbes plus their physico-chemical environment

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An ecosystem is a natural system consisting of all plants, animals and microorganisms (biotic factors) in an area functioning together with all the non-living physical (abiotic) factors of the environment. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. Ecosystems are defined by the network of interactions among organisms, and between organisms and their environment.

The two components of an ecosystem are 

  1. Biotic and abiotic

  2. Plants and animals

  3. Weeds and micro-organism

  4. Plants and light
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Two main components exist in an ecosystem: abiotic and biotic. The abiotic components of any ecosystem are the properties of the environment; the biotic components are the life forms, that occupy a given ecosystem. 

Examples of abiotic components are temperature, average humidity, topography and natural disturbances. 
Examples of biotic components are producers, such as plants and consumers, such as humans.

Ecosystems may be defined as

  1. A species along with environment

  2. Plant found in water

  3. Plants found on land

  4. All plants and animal species along with environment
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An ecosystem includes all the living organisms and all the nonliving components of their environment. It comprises of all living things namely plants, animals and organisms interacting with each other and also with their non-living environments, that is earth, air, water, sun, soil, climate, atmosphere, etc. 

Each ecosystem is unique and has three basic components that are autotrophs, heterotrophs and non-living matter. Most autotrophs in an ecosystem are plants while most of the heterotrophs are animals. 
Thus, the correct answer is option D.
