Which matter cycle is MOST highly dependent on processes carried out by soil bacteria?
Answer:
I guess nitrogen cycle since rhizobium plays an important role in nitrogen cycle and it lives on the root nodules of leguminous plants in the soil.
The nitrogen cycle is VERY dependent on the processes carried out by soil bacteria.
What do you mean by nitrogen cycle?The nitrogen cycle is a biogeochemical cycle in which nitrogen changes into several chemical forms as it circulates between atmospheric, terrestrial and marine ecosystems. Nitrogen transformation can occur through both biological and physical processes.
The nitrogen cycle is a repeated cycle of processes in which nitrogen passes through living and non-living things: the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is important because nitrogen is an essential nutrient for life on Earth. Nitrogen is an important component of amino acids, the building blocks of proteins, and nucleic acids, the building blocks of genetic material.

Why do carnivorous plants eat insects?
Answer:
Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Most plants absorb enough nitrogen from nitrates in the soil. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead. Carnivorous plants have developed unique ways to catch insects, such as fluid-filled PITCHERS and spring-loaded traps.

An invasive species is an organism that’s not native to a particular ecosystem but ends up invading the region. The populations of invasive species can rise sharply, in part because the species may not have natural predators to control their populations.
The graph shows the population of an invasive tree species spreading through a region. This tree has an earlier reproduction and growing season than many of the native trees. Give three examples of how this tree could affect competition with the native species of plants and animals in the forest.
Answer:
The early reproduction and growing season indicates that these trees will sprout sooner than many native trees. Because all trees need space to grow, the invasive tree species can reduce available space for native species to grow.
As the trees grow, they could limit sunlight availability for other species of trees and plants in the area.
Some plant-eating animals may rely specifically on native tree species for food. If the invading tree species reduces the supply of the native tree species, competition among the animals may increase.
Explanation:
This is the exact answer from edmentum, so you might wanna change it a bit. :)
These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.
What is Invasive species?All trees require area to grow, thus invading tree species may make less room for native species to spread out. As the trees develop, they may reduce the amount of sunlight that is available to nearby tree and plant species.
Some animals that consume plants might only consume local tree species. Competition between the animals may worsen if the invasive tree species lowers the availability of the native tree species.
Animals or plants that are invasive are those from another part of the planet that don't belong in their new habitat. Ship ballast water, an unintentional release, and individuals are the most common ways that they are introduced to an area.
Therefore, These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.

Why do you think naming the lynx might be advantageous for its survival? (please help)
Answer:
Lynx are wild animals, which act as predators in regulating the populations of their prey.
Lynx are dangerous for humans but humans are more dangerous for them because they are hunted for their skin.
Naming the lynx will be advantageous for its survival because it will give them a unique identity and will increase care for them. Naming the animal create a different bond between human and animals which changes the way humans regard animals.
So, naming the lynx might decrease the hunting of lynx and will increase its chnaces to survive.
In what type of rock do paleontologists generally look for fossils?

Calculate how much DDT you would consume if you ate 3 kg of squid (calamari).
Answer:
66 000 mg or 66g
Explanation:
If a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.
What effect does DDT have on animals?DDT is commonly used in pest control, but it is eventually replaced by other chemicals due to its numerous environmental side effects, which include the thinning of eggshells in birds, accumulation in the fatty tissues, disruption of the endocrine system of animals, etc., and being highly toxic to animals and birds, etc.
Hence, if a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.

What is the connection between the rising concentration of SO2 And NO2x , And The Acid Rain Pollution Alert?
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
