Question

Accepted Answer

### Question 1
# Brief Explanations:
The question is about ecological organization levels. An ecosystem consists of communities (biotic) interacting with non - living (abiotic) parts of the environment.
# Answer:
Ecosystem

### Question 2
# Brief Explanations:
A cow is a herbivore (eats plants), a primary consumer (feeds on producers), and can be described as a heterotroph (cannot make its own food). These terms are based on the ecology pyramid.
# Answer:
Herbivore, Primary Consumer, Heterotroph

### Question 3
# Brief Explanations:
In a food chain, secondary consumers are carnivores or omnivores that eat primary consumers (herbivores). For example, a fox (secondary consumer) eats a rabbit (primary consumer).
# Answer:
Primary Consumers

### Question 4
# Brief Explanations:
In a trophic pyramid, energy decreases as we move up trophic levels. Producers (first trophic level, like plants) have the most energy because they capture energy from the sun through photosynthesis, and only a fraction of energy is passed to the next level.
# Answer:
Producers (First Trophic Level)

### Question 5
# Brief Explanations:
Decomposers (like bacteria and fungi) break down dead organisms and organic matter, recycling nutrients back into the ecosystem. They decompose complex organic materials into simpler substances.
# Answer:
Decomposers break down dead organisms and organic matter, recycling nutrients back into the ecosystem.

### Question 6
# Brief Explanations:
- Abiotic factors are non - living components of an ecosystem. Examples include sunlight, water, temperature, soil.
- Biotic factors are living components. Examples include plants, animals, bacteria.
# Answer:
- An abiotic factor - Sunlight (or Water, Temperature, Soil etc.)
- A biotic factor - Grass (or Rabbit, Bacteria etc.)

### Define a biosphere
# Brief Explanations:
The biosphere is the global sum of all ecosystems. It includes all living organisms on Earth and the areas (land, water, air) where they live, interacting with each other and the non - living environment.
# Answer:
The biosphere is the global sum of all ecosystems, including all living organisms and the environments (land, water, air) they inhabit, with interactions between living and non - living components.
