Fill in the blanks :
In ecosystem dominated by trees, the pyramid (of number) is ............type .

Answer

To answer the question, we need to analyze the structure of a pyramid of numbers in an ecosystem dominated by trees. Here’s a step-by-step breakdown:

1. **Understanding Ecosystems**: An ecosystem consists of various organisms that interact with each other and their environment. In this case, we are focusing on an ecosystem dominated by trees.

2. **Pyramid of Numbers**: The pyramid of numbers represents the number of individual organisms at each trophic level in an ecosystem. The base of the pyramid consists of producers (like trees), followed by primary consumers (herbivores), and then secondary and tertiary consumers (carnivores).

3. **Dominance of Trees**: In an ecosystem where trees are the primary producers, there are typically fewer trees compared to the number of herbivores that feed on them. For example, one tree can support many herbivores, leading to a higher number of primary consumers.

4. **Shape of the Pyramid**: In this scenario, the pyramid of numbers will have a broad base (representing the trees) and a narrower top (representing the herbivores and carnivores). This structure is known as an "upright pyramid."

5. **Conclusion**: Therefore, in an ecosystem dominated by trees, the pyramid of numbers is an **upright** type.

Final Answer: In ecosystem dominated by trees, the pyramid (of number) is **upright** type.
