Ecosystem
An ecosystem consists of all the biotic and abiotic factors in an area and their interactions
<h3>What is an Ecosystem ?</h3>
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
- Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria
- While abiotic are non-living components; such as water, soil and atmosphere
- Ecosystems are all responsible for keeping the planet as a whole in balance. Animals and other life forms can only thrive if their ecosystems are thriving as a whole.

According to the gate control theory of pain, the structure that is the likely location of the gate is the substantia gelatinous.
<h3>
What is substantia gelatinous?</h3>
- A group of cells called the substance gelatinosa can be found in the spinal cord's gray matter (dorsal horns).
- It receives direct input from the dorsal (sensory) nerve roots, particularly those fibers from pain and thermoreceptors, and is present at all levels of the cord.
- The spinal cord has a system that permits pain signals to be amplified in the brain before being processed at the spinal cord itself, or attenuated there, in accordance with the Gate Control Theory of Pain.
- The "gate" is the device that either permits or forbids the transmission of pain signals.
- To feel intense pain if the gates are more open since many more pain signals will flow through to the brain.
- The likelihood that you will feel less discomfort increases as the gates are more tightly shut.

A. All four are protist membranes
b. Two are from the engulfed photosynthetic bacterium; one is a protist membrane; the other is from the food vacuole produced by the protist originally containing the bacterium.
c. Four membranes evolved from the protist's cell membrane.
d. All four are bacterial membranes.
e. One is from the bacterium; one is from the protist; one is from the bacterial nuclear membrane; one is from a food vacuole.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. ... By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system.
