The breakdown of pollutants, water purification and soil formation are valuable services provided by ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
There are four basic components of an ecosystem: abiotic substances, producers, consumers, and reducers, which are also known as decomposers. Abiotic means that a substance is devoid of life, it is physical and not derived from living organisms.
Ecosystems are organized to better understand the frame of reference in which they are being studied. They are organized from smallest to largest; organism, population, community, ecosystem.

5.explain mastication peristalsis segmentation and the release of hormones and enzymes necessary for digestion
Answer:
Ingestion starts both chemical and mechanical digestion.The digestion process begins with ingestion. The teeth starts the process of digestion by masticating food. Mastication makes easier swallowing and faster chemical breakdown. During mastication, salivary glands secrete saliva to soften the food. Saliva contains the salivary amylase enzyme, which digests carbohydrates, and mucus, which softens food into a bolus.
Peristalsis is a series of wave-like muscle contractions that moves food. Segmentation involves contractions of the circular muscles in the digestive tract, and Mastication breaks down food so that it can go through the oesophagus to the stomach.
Hormones - The hormones released by the pituitary gland are gonadotropins (LH and FSH), growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), prolactin, antidiuretic hormone and oxytocin.
Enzymes - Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach. Pepsin helps break down proteins into amino acids.
Trypsin, produced in the pancreas. Trypsin also breaks down proteins.
Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
Explanation:
So we can conclude that,
mastication peristalsis segmentation is
breaking down food in a wave like muscle contractions of the circular muscles in the digestive tract.
Btw I am not really sure about it.
Mark as brainliest!
Answer:
Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into sub units that are small enough to be absorbed by the lining of the alimentary canal. This is accomplished by enzymes through hydrolysis. The many enzymes involved in chemical digestion are summarized

As a population of a species increases within a territory, which of the following most likely also increases?
A-immigration
B-carrying capacity
C-food supply
D-competition
Answer:
D) competition
Explanation:
They are going to be competing for their survival.
Hope this helps! :)
With the increase in the population of a species, the competition between them also increases.
How competition affect a population?An association between two or more individuals of the same population or two or more populations in which each negatively influences the other in access to a restricted resources like food, shelter, water, mates, nesting, etc is termed competition.
When the size of a population increases, one can witness more intense competition between the individuals of the population. The influence of competition is generally density-dependent, that is, at greater population density, there is an increase in competition. This will negatively affect the size of the population.
Thus, the correct answer is option D, that is, competition.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be
present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

what is the difference between hatcheries and fisheries
Hatcheries provide artificial shelter for fish versus the natural shelter found in a stream.
Compared to hatchery fish, wild fish are usually more successful at surviving the rigors of the natural environment long enough to reproduce. Fewer than 1% of the smolts released from the hatchery return home to spawn.
Answer:
Hatchery: A facility where eggs are hatched under artificial conditions, especially those of fish or poultry.
Fishery: Fishing: the catching, processing and marketing of fish or other seafood.

Bacteria are good as well bad for human body.For muscle development it is needed as it have some properties of muscle repairing.As, Bacteria is unicellular micro organisms. It have cell wall. The bacteria which are beneficial they defence the unnecessary bacteria and increases our immune which helps to repair muscles.Bacteria break down biological waste and they build up strong immune system. They control our mechanism for muscles.These were some reason.

This part is used to bring the specimen into sharp focus. This part causes a very small up and down motion when used.
Answer:
Fine focus.
Explanation:
If you're referencing a microscope, then it would be fine focus. Coarse focus is a basic focus used to properly see a specimen, while fine focus enhance clarity and precision. To use both, you have to gently twist a knob until you can see the specimen at a desired clarity.
