Why are human populations not limited by the carrying capacity of their ecosystems?
exis [7]

Answer:

humans use their knowledge to locate resources.

Explanation:

The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.  

The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.

Was I correct? <br><br> The question was “What is the best solution for maintaining biodiversity?”
hoa [83]

Answer:

Yes

Explanation:

Indeed, <u>the best solution for maintaining biodiversity is to conserve the biodiversity of every ecosystem, since all ecosystems have benefits to humans and the earth</u>.

Ecosystems might vary in the kind of services they render to the planet or humans in general. For example, the forest ecosystems supply humans with the necessary timber and wood for construction purposes and sequestrate carbon/produce oxygen from and to the environment respectively. Thus, the forest ecosystem plays a huge role in maintaining the air quality of the planet in addition to several other services.

The variation in the services the different ecosystems render to the human population and the planet necessitates that the biodiversity of every one of them be conserved. Prioritizing the conservation of one over the other will result in losing some of the services provided as a result of loss of biodiversity.
