Which question would BEST help an investigation of whether or not an ecosystem has reached carrying capacity?

Question 2 options:

How many offspring do the keystone species in this ecosystem produce each season and how many in their most recent births?

What is the maximum amount of species the ecosystem has supported and how many are supported currently?

What is the comparison of the average rainfall over two years in an ecosystem?

Where on a logistic growth curve are the lowest amount of species in this

What is the maximum amount of species the ecosystem has supported and how many are supported currently?

Explanation:

The carrying capacity of any species in an environment refers to the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat , water , and other necessities available in the environment. It is also defined as the environment's maximal load. Hence, the carrying capacity can summarily be perceived as the number of individuals an environment can support without significant negative impacts to the given organism and its environment. Below carrying capacity, populations typically increase, while above, they typically decrease.

By comparing the maximum amount of species that the ecosystem has supported overtime and the number of species that the ecosystem currently supports, we could have an idea if the ecosystem has exceeded the amount of organisms that it can normally support without negative effects - its carrying capacity

yes it is weird but true

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
