So that they don't argue over results when two types of measurements equal the same thing but are just put differently
A large number of living organisms obtain energy by cellular respiration
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.
Answer:
c. The flea beetle can become an invasive species
Explanation:
An invasive species is a non-native species that is introduced to the population (for example by humans). Because they are non-native, they can disrupt the 'natural order' of things. I.e., they can change the function of the ecosystem, which develops naturally to result in a harmony.
In this example, the leafy surge is a good example of an invasive species, it was accidentally introduced and has grown out of control, damaging the range land. In an attempt to control this, we deliberately introduced <em>another non-native species</em>.
This is in an attempt to fix the original mistake. If it works, then great! But if the flea beetles don't actually eat the leafy spurge, and they reproduce so quickly... it means we have introduced an additional species that could also disrupt the ecosystems. This could then mean that the flea beetle becomes an invasive species.
