The provided statements A, B, C, D, and E describe processes within the detritus food chain. However, D and E are inaccurate:
D: This statement suggests that the detritus food chain commences with living organisms, which is incorrect.
In reality, it begins with dead organic matter.
E: The statement incorrectly labels the process of breaking down detritus into simpler forms as "catabolism," specifically attributed to earthworms. In truth, this process does not have a specific term and is not solely carried out by earthworms.
Conversely, statements A, B, and C accurately represent processes within the detritus food chain.
Therefore, the correct option is (D) : A, B, C only.
In the equation GPP - R = NPP
GPP is Gross Primary Productivity
NPP is Net Primary Productivity
R here is ________.
Given below are two statements:
Statement I: Gause’s ‘Competitive Exclusion Principle’ states that two closely related species competing for the same resources cannot co-exist indefinitely and competitively inferior one will be eliminated eventually.
Statement II: In general, carnivores are more adversely affected by competition than herbivores.
In the light of the above statements, choose the correct answer from the options given below:
List I | List II | ||
---|---|---|---|
A | Mesozoic Era | I | Lower invertebrates |
B | Proterozoic Era | II | Fish & Amphibia |
C | Cenozoic Era | III | Birds & Reptiles |
D | Paleozoic Era | IV | Mammals |
An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.
The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
There are two main components of the structure of an ecosystem, namely:
The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
