Let's analyze the problem step-by-step:
1. Data Analysis from the Table:
The table provides the number of species and total organisms in four ecosystems.
| Ecosystem | Species | Organisms |
|-----------|---------|-----------|
| 1 | 62 | 2,000 |
| 2 | 32 | 2,000 |
| 3 | 104 | 2,000 |
| 4 | 8 | 2,000 |
2. Finding the Most Diverse Ecosystem:
The diversity of an ecosystem can be evaluated based on the number of species it contains. Among the given ecosystems:
- Ecosystem 1 has 62 species.
- Ecosystem 2 has 32 species.
- Ecosystem 3 has 104 species.
- Ecosystem 4 has 8 species.
Therefore, the most diverse ecosystem is Ecosystem 3, as it has the highest number of species, which is 104.
3. Details in the Second Ecosystem:
In Ecosystem 2, the species are distributed as follows:
- Producers: 4 species
- Primary Consumers: 8 species
- Secondary Consumers: 10 species
- Tertiary Consumers: 10 species
The total number of species in Ecosystem 2 initially is:
[tex]\[ 4 + 8 + 10 + 10 = 32 \text{ species} \][/tex]
4. Increase in Primary Consumers:
If the number of primary consumers increases to 20, the new distribution will be:
- Producers: 4 species
- Primary Consumers: 20 species
- Secondary Consumers: 10 species
- Tertiary Consumers: 10 species
The new total number of species in Ecosystem 2 would be:
[tex]\[ 4 + 20 + 10 + 10 = 44 \text{ species} \][/tex]
5. Calculating the Increase in Species:
The increase in the number of species due to the change is:
[tex]\[ 44 - 32 = 12 \text{ new species} \][/tex]
Thus, summarizing our findings, the correct answers for the dropdowns are:
- Among the four ecosystems, Ecosystem 3 is the most diverse.
- In the second ecosystem, if the number of species of primary consumers increases to 20, there will be 12 new species.
So the completed sentences are:
- Among the four ecosystems, Ecosystem 3 is the most diverse.
- In the second ecosystem, if the number of species of primary consumers increases to 20, there will be 12 new species.
