Over time, some plants growing in an area are crowded out by other plants. the new plants use up water and nutrients needed by the previous plants. the disappearance of the first plants is due to:

Competitive exclusion

Explanation:

According to competitive exclusion principle two species cannot exist together if these species share the same habitat and resources. This principle was given by the scientist Georgy Gause.

Some plants that are growing in an area are crowded by other plants over time. The new plants use water, nutrients and the first plants are disappeared because both plant species share same resources and habitat. These two species cannot co exist and the second plant causes the disappearance of plant because of competitive exclusion.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
