Final answer:
The correct statement is: Humans have really altered the biomass of the planet.
The answer is option ⇒4
Step-by-step explanation:
Based on the given information, let's evaluate each statement:
1) The mass of humans plus their livestock outweigh wild animals by more than 50:1.
This statement cannot be determined from the given figure alone. The figure does not provide information about the mass of humans, their livestock, or wild animals. Therefore, we cannot conclude whether the mass of humans plus their livestock outweigh wild animals by more than 50:1.
2) There are two very big fish in a fish tank.
This statement cannot be determined from the given figure. The figure does not depict a fish tank or provide any information about the number or size of fish in it. Therefore, we cannot conclude that there are two very big fish in a fish tank based on the figure.
3) We are at global carrying capacity.
The figure does not provide information related to global carrying capacity. Global carrying capacity refers to the maximum number of individuals of a species that can be sustained by a particular environment. Without any specific data or context related to population size or resource availability, we cannot determine if we are at global carrying capacity based on the figure.
4) Humans have really altered the biomass of the planet.
This statement is supported by the given figure. The figure clearly demonstrates that the biomass of humans, represented by the orange section, is much larger in comparison to the biomass of wild animals, represented by the small green section. This indicates that humans have significantly altered the biomass distribution on the planet.
In summary, based on the given figure, the correct statement is:
- Humans have really altered the biomass of the planet.
The answer is option ⇒4
