Explanation:
1. As earthworms dig through the soil, they create passages that help air and water circulate. This helps plant roots get the oxygen they need to grow.
These tunnels also help improve the excess water seeping into the soil.
2. Earthworms consume dead plants and animal matter, which breaks it down into smaller pieces. This organic matter can provide nutrients to plants.
3. Earthworm castings, or poop, are a nutrient-rich fertilizer that helps plants grow.
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:
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.
