Answer:
B. a light bulb burned out and "closed" the circuit.
Explanation:
Unscrew one bulb. If the other bulbs turn off, it is a series circuit. A light bulb glows when electrons flow through it. As the electron flow increases, the brightness increases.
When lights are attached in parallel, each light is on its own circuit to the power source. If one filament burns out, it has no effect on the remaining lights, as they each continue to be in a closed circuit with the power source.

Answer:
Increased keystone species
Explanation:
An organism is a keystone species when it contributes to the definition of a given ecosystem such that the absence of the keystone species in an ecosystem, the ecosystem will change dramatically or be gradually wiped out
The effect of the keystone on its environment is unevenly large when compared to its abundance relative among other organisms within the ecosystem
The keystone is therefore, a prime source of balance of nature, diversity and well-being of the ecosystem
Therefore, the option that contributes to the diversity of the ecosystem is;
Increased keystone species.
