Ecology is the study of how organisms interact with their environment, including both abiotic (non-living) and biotic (living) aspects of the environment. It is a very broad definition and the science of ecology tends to overlap other biological sciences.
Answer:
substitution is the Answer
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
The correct answer is C. An ecosystem service
Explanation:
In ecology, an ecosystem service refers to processes or elements that are part of the natural environment but besides this represent benefits for humans, this includes organisms and processes involved in the decomposition of waste and also pollination. Pollination is an example of an ecosystem service because, in pollination insects, birds and other organism or even wind transfer pollen which makes possible plants fertilization and this is essential for crops in agriculture, which means humans benefit for pollination and therefore this is an ecosystem service.
