Answer:
The correct answer is : oxygen
Explanation:
- Oxygen is carried in the blood by two means:
- About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
- Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.
- RBCs lack nucleus. This place is occupied by hemoglobin molecules that binds to oxygen and form oxy-hemoglobin.
- This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.

Answer:
Explanation:
(a) interspecific competition: It is a kind of competition that occurs between the individuals that belong to different species competing for the same resource in an ecosystem. For example, lion and tiger populations thriving for the same type of prey that is deer population.
(b) intraspecific competition: Interspecific competition occurs between the members of the same population competing for limited resources. For example, trees of the same species competing for the sunlight and soil nutrients.
(c) predation: It is an ecological interaction that occurs between the superior or inferior species. One animal kills other animal to obtain it as a source of food. For example a tiger kills a deer to obtain it as food.
(d) territoriality: It is a quality of a species or a population of species to obtain the geographical area to an extent or limit where no other species or population can intrude. For example, lion shows the territory behavior to protect their children from predators.
(e) symbiosis: It is a type of biological interaction in which two species lives in association with each other. This interaction can be mutualistic, parasitic or commensalistic. For example, a lice sucking blood from animal is an example of parasitic symbiosis.
