keystone species which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
These predators would belong to keystone species. The correct option is B.
Thus, Predators at the highest levels are frequently regarded as keystone species in an ecosystem. Compared to their biomass or abundance, keystone species have a disproportionately strong influence on the composition and operation of their ecosystem.
They are essential in maintaining the ecosystem's balance and preventing the overpopulation of particular species by controlling the populations of other species there.
The dynamics and biodiversity of the ecosystem can be significantly impacted by the removal of a keystone species.
Thus, These predators would belong to keystone species. The correct option is B.

According to the leading theory today, how does the composition of the inner and outer core cause Earth's magnetic field?
Answer:
electric things
Explanation:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core these convection currents are caused by heat escaping from the core a natural process called a geodynamo.
The composition of the inner and outer core cause Earth's magnetic field by a process called geo dynamo
What is Geo dynamo?Geo dynamo is the process where electric current generates the magnetic field due to convection currents where the inner and outer cores are iron and nickelThese convection currents are caused by heat escaping from the core. the inner and outer cores are iron and nickel spins and generate the earth’s magnetic field.
