Worked Solution & Example Answer:Answer the following questions in relation to your study of ecology - Leaving Cert Biology - Question 2 - 2006
Step 1
What is the biosphere?
Answer
The biosphere refers to the regions of the Earth where life can exist. This includes all ecosystems and living organisms present on the planet, spanning land, water, and the atmosphere. It encompasses various habitats and interactions of organisms in these environments.
Step 2
What is meant by a qualitative survey?
Answer
A qualitative survey is a research method used to collect descriptive data about species, organisms, or types present in a given area. It typically focuses on non-numerical information, allowing researchers to gather insights and observations regarding the diversity and behavior of species without quantifying their abundance.
Step 3
Construct a grazing food chain containing at least four trophic levels.
Answer
A simple grazing food chain could be:
- Grass (Producer)
- Grasshopper (Primary Consumer)
- Frog (Secondary Consumer)
- Snake (Tertiary Consumer)
This illustrates the flow of energy and nutrients from the producer to the top predator.
