Explain the importance
of decomposers to the overall
biogeochemical cycle.
Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
Decomposers are essential for the biogeochemical cycle as they facilitate the recycling of nutrients, provide energy for other organisms, and help maintain the health and balance of ecosystems by Breaking down organic matter, Recycling nutrients, Energy flow and Detoxification.
Without decomposers, organic matter would accumulate, nutrients would become locked up, and energy flow within ecosystems would be disrupted.
Decomposers play a crucial role in the overall biogeochemical cycle. Here's why they are important:
Breaking down organic matter: Decomposers, such as bacteria and fungi, break down dead plants, animals, and other organic materials into simpler compounds. They do this through the process of decomposition, where they release enzymes that break down complex molecules into smaller, more manageable forms.
Recycling nutrients: By decomposing organic matter, decomposers release essential nutrients back into the ecosystem. These nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are then made available for uptake by plants and other organisms. This recycling of nutrients is vital for maintaining the balance and productivity of ecosystems.
Energy flow: Decomposers also play a crucial role in energy flow within ecosystems. When they break down organic matter, they release energy in the form of heat. This energy can then be used by other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers (carnivores), to carry out their life processes.
Detoxification: Decomposers are capable of breaking down and detoxifying harmful substances and pollutants in the environment. For example, certain bacteria can break down pesticides and other chemical pollutants, helping to reduce their negative impact on the ecosystem.

Answer:
its transformation! so option B
Explanation:
Within the image you can see the final product is a "Genetically Transformed cell" and within lesson 03.01 HONORS on flvs there are multiple dropdowns giving definitions. one of these dropdowns contains this exact image, and it is titled 'Transformation' in the lesson.
I am currently taking this course, so actually searched brainly for that answer initially. I decided to take the test and come back with the right answer to help any other students like me! A tip for taking tests on flvs: You can have flvs open on multiple tabs, so the best way to take tests like this is to have the test open on one tab, and the lesson plan on another tab. That way you can read through the lesson and look at any graphs while actively in the test! Hope I could help at least a little, have a great school year everyone.

b. butterfly wings are assessed to see which is the most orange in appearance
c. the height of radish seedlings is measured
d. the odor of different plants is compared to see which smells the worst
Answer:
c. the height of radish seedlings is measured
Explanation:
Quantitative measurements revolve around the quantity of things and exact measurements. The measured height of a radish seedling is the perfect example of that.
Memory technique:
Quantitative observations involve quantity (numbers).Qualitative observations involve quality (descriptions, features, i.e. color, smell, shape)The stems and fruits of pineapple plants contain a group of protein-digesting enzymes collectively
called bromelain and often used as an antibrowning agent for fruits and vegetables. Fruits and
vegetables brown when they are bruised during transport or sliced and exposed to air. This browning is
controlled by enzymatic pathways that produce brown pigments. The browning of fruits and vegetables
reduces the nutritional value of the food, so antibrowning agents such as bromelain are used.

Geckos are a type of small lizard that live in tropical areas. Geckos are often eaten by birds, snakes and larger lizards so they need to blend into their surroundings. In one area, scientists had always found brown and green geckos that blended in with the grass and the leaves on the ground. Over time, though they found yellow geckos in the same population. Three students were talking about why there were yellow geckos. Ciena thought that the change came from a mutation in the population. Tibor thought the change came from the environment. Sasha though that Ciena and Tibor were both right. Who do you agree with and why do you think that?
Answer:
Not going to say this is right but, I think that Tibor is correct because if the land has changed more over time then the yellow ones have adapted to the new living conditions while the green one have found ways to live in that environment.

Predicting how the utilization of nonrenewable resources impacts the dom in the deep ocean
system?
Answer:
Non-renewable energies such as those derived from oil affect the seabed in a serious and lethal way for its fauna / flora.
When oil fields are drilled or when they have losses, they flood the seas with oil, these seas, having living organisms, will be directly affected in a lethal way by this unexploited fuel.
In addition, petroleum derivatives such as naphtha are used for water cars such as boats that pollute the water
Explanation:
Environmental awareness led to the search for an alternative as a source of energy that are renewable sources, which make a lot of competition today to polluting or non-renewable sources.
In addition, it must be considered that the pollutants have a limit, since they are exhausted, and on the other hand, an economy that solvent and supports all the expenses of the extraction of these from the depths of the seas is needed.
Answer: When coal and oil are burned, they release particles that can pollute the air, water, and land. ... Burning fossil fuels also upsets Earth's “carbon budget,” which balances the carbon in the ocean, earth, and air. When fossil fuels are combusted (heated), they release carbon dioxide into the atmosphere.

Explanation:
The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.
