The answer is; D
The angle at which the sun rays strike the earth at the equator is more or less 90 degrees while you move towards the poles, it much less than this. This means that the unit of sunlight per surface area received at the equator is higher than that at the poles. This is why the equator is always warmer than the poles.
These types of nerves are called "Sensory Neurons" :)
Sam is studying the interaction between porcupines, pinion pine trees, and pine bark beetles. Over the course of his study in Colorado, he observes the behaviors of 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles.
His study include 3 populations
- Population ecology is the study of the factors influencing the number and distribution of animal and plant populations.
- The study of the development, control, and interactions of animal populations is known as animal population ecology.
- A population's growth may be significantly influenced by the behavior of its constituent individuals, and the presence of predators, prey, and competitors in the community will also have significant effects.
- The population is a level of organization that lies between individuals and communities, but there is no clear distinction between the phenomena that affect these levels and those of the population.
- Here Sam studies 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles. hence 3 populations are being studied here.
