The ecosystem requires a constant input of energy because energy cannot be stored. The enrgy always gets converted for supporting life in the ecosystem. Some amount of energy is also lost during this conversion. So if there is not a constant supply of energy, then the ecosystem will ultimately breakdown. In case of humans, the energy is received by consuming food. The energy of the food geets converted to the enrgy that helps a human being to complete his daily chores. So energy is being lost at every step. To regain this energy the humans have to eat food regularly. This way the humans need a constant supply of energy to survive. It is the same in the case of all living things in the ecosystem.
kinetic energy
The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
The answer is d) organic chemistry
Answer:
The most important abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.
The advantage of this type of anatomical relationship is that this enables the pituitary to receive signals before sending hormones to the rest of the body through the blood.
The anterior pituitary, a significant component of the endocrine system, is the glandular anterior lobe that, along with the posterior lobe (also known as the posterior pituitary or neurohypophysis), constitutes the pituitary gland (hypophysis).
Stress, growth, reproduction, and lactation are just a few of the physiological activities that the anterior pituitary controls.
Blood tests that assess hormone levels are frequently used to determine if the anterior pituitary and the organs it controls are functioning properly.
The hypothalamus-hypophyseal portal veins deliver hypothalamic releasing and inhibitory hormones directly to the anterior pituitary gland.
Certain hormones from the hypothalamus bind to receptors on particular anterior pituitary cells, controlling how much of the hormone they generate is released.
