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.

Global warming affect biodiversity by increasing temperatures mean increased risk of extinction and the correct option is option B.
Global warming has a detrimental impact on biodiversity, primarily increasing the risk of extinction for many species. Rising temperatures disrupt habitats, leading to habitat loss and reduced living space.
Species may struggle to adapt or migrate fast enough to keep up with changing conditions, resulting in range shifts and potential mismatches in ecological interactions.
Additionally, the specific temperature tolerances of many organisms are exceeded, making them vulnerable to heat stress, disease, and other pressures. While some species may exhibit adaptive responses, the overall consequences of global warming on biodiversity are negative, posing significant threats to the intricate web of life on Earth.
Thus, the ideal selection is option B.

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

Given the discussion thus far of commensalism and parasitism, would parasitism be an accurate way to describe the relationship between the strangler fig and the cypress tree?
please help me
The relationship between the strangler fig and the cypress tree closely resembles one of parasitism but is not. It is considered commensalism.
Parasitism is when one organism uses another as a host in order to survive, which generated negative impacts for the host, which will usually end in death. The strangler fig uses the tree as a host in order to sustain itself structurally but does not siphon nutrients from the tree or directly kill it, therefore it is not a form of parasitism.
Commensalism is described as a relationship between two organisms, in which the benefits are gained by only one of the members, but neither of the two is harmed in any way.
The relationship between the strangler fig and the cypress tree is best described as commensalism, given that although the strangler fig does eventually cause the tree to die by encircling its roots and not allowing it to grow, it does not kill the tree directly in order to survive.

explain the importance of understanding the process of evolution.
why is it important to study how species evolve over the time and how does this relate to their changing environments?
Answer:
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.
