How do matter and energy interact in a food web or energy pyramid model?
Answer: The higher up the pyramid the less energy there is.
Explanation: There is more competition
Answer:
At each link upward in a food web, only a small fraction of the matter consumed at the lower level is transferred upward, to produce growth and release energy in cellular respiration at the higher level. ... At each link in an ecosystem, matter and energy are conserved.

Which is a tertiary consumer in this food web?
Answer:
Look below.
Explanation:
A tertiary consumer is an animal that eat primary consumers and secondary consumers. From this knowledge we can conclude that the tertiary consumer is the mountain lion since nothing consumes the animal and it is on the top of the food web for consuming the most energy.
Answer:
The Mountain Lion
Explanation:
In a food web the arrows indicate energy being transferred to the animal it's pointing to from the animal it's pointing away from. In other words the arrow points at the animal that ate the one it is pointing away from. Since the Mountain Lion has the most arrows pointing to it, it's the highest predator in this food web. Since it is at the top it is a tertiary consumer.

1. Which of the following is NOT a key factor important to the development of human society?
A. Access to clean water
B. Access to fertile soil
C. Access to cities
D. Access to natural resources
Access to cities is not a key factor important to the development of human society, but clean water, fertile soil, and Access to natural resources all are needed, hence option C is correct.
What are factors important to the development of human society?The preagricultural (hunting and gathering) stage, the agricultural stage, and the industrial stage are thus the at least three primary stages of societal evolution or civilizations.
Clean water is essential to our way of life because it creates a habitat for species and places to fish, paddle, surf, and swim. Our economy is reliant on clean water to operate and thrive. This includes industries like manufacturing, agriculture, tourism, recreation, and energy generation.
They support tax revenue, income, and the fight against poverty. Natural resource-related industries generate employment and frequently form the backbone of poorer towns' economies.
Therefore, natural resources are fundamentally important, so they must be managed responsibly.

How does blood help maintain the homeostasis in the body?
Answer:
Blood absorbs and distributes heat throughout the body. It helps to maintain homeostasis through the release or conservation of warmth. Blood vessels expand and contract when they react to outside organisms, such as bacteria, and to internal hormone and chemical changes.

Explanation:
If a couple has four daughters the % chance of their next child being a daughter is
Answer:
50% chance
Explanation:
Humans have two sex chromosomes, the X chromosome and the Y chromosome. Males inherit both X and a Y chromosome, while females inherit two X chromosomes. Thus, the sex of the child is determined by the sex chromosome carried by the male gamete (i.e., X or Y chromosome) which fuses with the egg cell (always containing an X chromosome). In consequence, the chance of having a sperm containing an X chromosome (i.e., the chance of having a girl) is an independent event of previous fertilization events (which led to the formation of 4 different female zygotes), thereby the probability will be 50%.
Which of the following is NOT in part of the natural selection process?
A. a species produces more offspring than can survive
B. an organism adapts to their environment causing variation
C. individuals competing with each other
D. fossils being formed
Answer:
the selection that is not a natural selection process is D: fossils being formed
Answer:
D. Fossils being formed
Explanation:
In the natural selection process, the point is that the animal which is best adapted to the environment survives, so their offspring can survive and produce more offspring that adapts. This is because organisms need to adapt to their environment to survive. Without natural selection, most animals would be too weak to live in their own habitat.
So when we see the answer choices, we have to ask if the species could continue to live and adapt.
A- the species produces more offspring that can survive. Yes, the species can continue to live and adapt.
B- an organism adapts to their environment. Yes, the species can continue to live and adapt.
C- individuals competing with each other. Yes, the better species will win, and continue to live and adapt
D- fossils being formed. No, this has nothing to do with the process of living and adapting. It is in fact the opposite, since it relates to the species dying.
So the answer is D
Which has a lower albedo, a black sheet of paper or a white sheet of paper?
Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo
Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
Answer:
osmosis
Explanation:
plants use osmosis whic is moving water though a semipermial membrane to draw up water. It moves from places of high conetartions of water (dirt) has to is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.
Plants use osmosis which is moving water though a semipermial membrane to draw up water.
What do you mean by osmosis?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.
