2.1. Name the organism above that represents a: (a) Carnivore (b) Producer. 2.2.2. If only the above food chain exists in an ecosystem, explain the effect of the death of the greenfly in that ecosystem.

a) A carnivore is an organism that feeds on other animals. In this food chain, the Ladybird eats the Greenfly, and the Blackbird eats the Ladybird. Both are carnivores.

b) A producer is an organism that produces its own food, typically through photosynthesis. The Rose is a plant, making it the producer.

$$\boxed{\text{a) Ladybird / Blackbird}}$$ $$\boxed{\text{b) Rose}}$$

If the greenfly population dies out:

• The Ladybird population will decrease significantly or die out because greenflies are their primary food source.
• Consequently, the Blackbird population will also decrease due to the lack of ladybirds, their food source.
• The Rose population may increase because there are no greenflies to feed on them.
