Answer:
Concentration gradient
Explanation:
When the concentration of molecules and ions is compared to the concentration of ions and molecules in another area, the difference in the concentration will be called the concentration gradient.
The concentration gradient is the factor which determines the rate and direction of the molecules and ions in the environment which could be physical or biological.
Thus, concentration gradient is the correct answer.
When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated this process called as adaptive radiation.
<h3>What is Habitat?</h3>
The term "habitat" in ecology refers to the variety of resources, physical characteristics, and biotic elements that exist in a region and are necessary for a specific species to survive and reproduce. An animal's habitat can be thought of as the outward representation of its biological niche.
Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type."
The physical elements could consist of things like soil, moisture, temperature range, and light intensity, for instance. The availability of food and the existence or absence of predators are examples of biotic variables. Every species has certain habitat needs; habitat generalist species can survive in a variety of environmental circumstances, whereas habitat specialist species need a specific habitat.

Answer:
a) Toxic (gases)
d) Bacterial
Explanation:
Septic tanks are underground structures usually built with concrete or plastic in which wastewater is treated. These tanks are generally used in rural areas and are located near bathrooms and laundry rooms.
If a septic tank is working correctly, it should produce any unpleasing smell. However, when an individual perceives a certain strong bad smell it could be due to the presence of gases (low levels of hydrogen sulfide and high levels of carbon dioxide, and methane) and anaerobic microorganisms such as sulfur bacteria which also produce methane and, therefore, strong smell.
It all depends of what kind of bad smell is the person perceiving. For example, the smell of "rotten egg" is usually due to microbial pollution and gases. Although these gases are not toxic in low levels, they could become highly toxic. It is extremely important to pay attention to smell and give the appropriate mainteinance.
