Question

q.1. the diagram below shows a simple food chain.which organism is the producer in this food chain?a) carrots b) rabbitc) fox d) lionuse the food web below to answer the next three questions. (q.2 - q.3 - q.4)q.2. which organism does the mouse eat?a) wild cat b) plantc) snake d) owlq.3. what is the source of energy for the plant?a) rabbit b) goatc) mouse d) sunlightq.4. if additional jackals are introduced into this ecosystem, there will most likely be an immediate decrease in the ____________.a) lion population b) plant populationc) goat population d) wild cat population

Explanation:

• Q.1: Producers are organisms that can make their own food through photosynthesis. In a food chain, plants are typically producers. Carrots are plants, while rabbit, fox, and lion are consumers.
• Q.2: Looking at the food web, the mouse is shown to eat plants. Wild cat, snake, and owl are predators that may eat the mouse, not the other way around.
• Q.3: Plants get their energy from sunlight through the process of photosynthesis. Rabbit, goat, and mouse are consumers and do not provide energy to the plant.
• Q.4: Jackals are predators. If more jackals are introduced, they will likely eat more of their prey. In the food web, jackals eat goats. So there will be an immediate decrease in the goat population. Lion population may be affected later if there's less food (e.g., from jackals reducing goat numbers which could affect lions if they also rely on goats, but the immediate effect is on the prey of jackals). Plant population is more indirectly related (if goat population decreases, plant population might increase as there are fewer goats eating them). Wild cat population is not directly preyed on by jackals in this simple analysis of the food - web shown.

Answer:

• Q.1: A. Carrots
• Q.2: B. Plant
• Q.3: D. Sunlight
• Q.4: C. Goat population
