Select the correct answer from each drop-down menu.

The table lists the number of species and total organisms found in four ecosystems.

\begin{tabular}{|c|c|c|}
\hline Ecosystem & Species & Organisms \\
\hline 1 & 62 & 2,000 \\
\hline 2 & 32 & 2,000 \\
\hline 3 & 104 & 2,000 \\
\hline 4 & 8 & 2,000 \\
\hline
\end{tabular}

Among the four ecosystems, [tex]$\square$[/tex] is the most diverse.

In the second ecosystem, there are 4 species of producers, 8 primary consumers, 10 secondary consumers, and 10 tertiary consumers. If the number of species of primary consumers in the second ecosystem increases to 20, there will be [tex]$\square$[/tex].



Answer :

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.
