What is ecology and how is it divided?
Ecology is a branch of biology focused on how organisms interact with each other and their environment. It's a vast field that's divided into multiple sub-disciplines. These include population ecology, studying groups of the same species, and community ecology, focusing on interaction between different species. Ecosystem ecology looks at energy flow and cycling of elements among organisms in a community and their environment. Lastly, there's global ecology that examines the biosphere and the large-scale interactions between organisms and the Earth.
