The geographic limit within which a population exists is called
-
Niche
-
Ecosystem
-
Habitat
-
Biome
Which one is not a component of environment?
-
Sunlight
-
Decomposers
-
Water
-
Air
Environment is defined as a natural ecosystem that includes everything around the biotic factors. These are nonbiotic factors. These includes air, water, sunlight. Decomposers are the biotic factors of an ecosystem.
Biotic components are dependent on abiotic components of environment.
-
True
-
False
Two species in the same habitat can coexist when they
-
differ in their use of resources
-
share the same resource in different ways
-
use the same resource at different times
-
all of these
2 species that are coexisting in a particular area have few characteristic features to avoid intraspecific competition.
An example of biotic components in nature is
-
Cells
-
Organic molecules
-
Plants
-
All of the above
Which of the following examples show the interdependency of biotic and abiotic factors?
-
Frigid climates do not support lizards and other cold-blooded animals
-
Relation between water and life
-
The need of sunlight for the process of photosynthesis
-
All of the above
- The biotic components of the ecosystem are the producers and consumers. The abiotic or the non-living components include soil, water, light, inorganic substances.
- Both biotic and abiotic factors are interdependent in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
- Examples showing the interdependency of biotic and abiotic factors include Frigid climates do not support lizards and other cold-blooded animals, Relation between water and life and the need for sunlight for the process of photosynthesis.
- So, the correct answer is 'All the above'.
An ecosystem is made up of one type of community.
-
True
-
False
-
Either
-
Neither
Which of the following are Edaphic factors?
-
pH
-
Minerals
-
Organic matter in soil
-
All of the above
- Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. For example, rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight.
- The edaphic factor is an abiotic factor relating to the physical or chemical composition of the soil found in a particular area. For example, the pH of the soil, Minerals present in the soil and organic matter in the soil.
- Hence pH, Minerals and organic matter in soil are examples for Edaphic factors because these are physical or chemical composition of the soil found in a particular area.
- So, the correct answer is 'All the above'.
Only living things form a part of our habitat.
-
True
-
False
Our habitat includes both biotic components like micro-organisms, plants, animal etc and also abiotic components like soil, water, atmosphere etc
