Answer:
keystone species
Explanation:
Keystone species are indispensable species that are essential to the maintaining of the balance of an ecosystem, and also play a major role in the way species in the ecosystem interrelate. The absence or removal of a keystone species from a habitat or ecosystem would lead to the disruption and imbalance of the ecosystem, and as such lead to the extinction of other species.
An example of a keystone species is the bee. Bees are very important in pollination of flowering plants and also ensure their survival. This plants serve as home to various insects that are source of food to birds. The removal of bees from this ecosystem would affect the ecological balance of this ecosystem.
Answer:
abundance and occurrence are linearly related
Explanation:
The core-satellite hypothesis states that several species will be widespread and several species will be scarce. This is based on the assumption or prediction that species habitation is distributed bimodally.
Hence, according to the core-satellite hypothesis, it is believed that "abundance and occurrence are linearly related."
As there is an increase in the level or number of species, the chance of occurrence or seeing their species increases.
