A food chain is a simplified way to show the relationship of organisms that feed on each other. It’s helpful to classify animals in a simple food chain by what they eat, or where they get their energy.
Green plants, called producers, form the basis of the aquatic food chain. They get their energy from the sun and make their own food through photosynthesis. In the Great Lakes, producers can be microscopic phytoplankton (plant plankton), algae, aquatic plants like Elodea, or plants like cattails that emerge from the water’s surface.
Herbivores, such as ducks, small fish and many species of zooplankton (animal plankton) eat plants. Carnivores (meat eaters) eat other animals and can be small (e.g., frog) or large (e.g., lake trout). Omnivores are animals (including humans) that eat both plants and animals. Each is an important part of the food chain.
In reality, food chains overlap at many points — because animals often feed on multiple species — forming complex food webs. Food web diagrams depict all feeding interactions among species in real communities. These complex diagrams often appear as intricate spider webs connecting the species.
This lesson demonstrates that changes in one part of a food chain or web may affect other parts, resulting in impacts on carnivores, herbivores, and eventually on producers. An example of this might be the harmful effects of pollution. The point that should be made is that when something disrupts a food web, humans should try to understand and minimize the disturbance. Students should also come to recognize that humans, too, are part of this complex web of life.

Some sugar molecules are absorbed from the small intestine into the blood by active transport. Explain why the rate of absorption of these can depend on the concentration of oxygen in the cells lining the small intestine?
Answer:
Because oxygen is the mediator of active transport.
Explanation:
The greater the oxygen, the greater the active transport, since it requires ATP and this energy currency requires cellular respiration.

which of the following is a biological aspect of an organism's niche?
A) the way it gets food
B) amount of sunlight
C) the water in the area
The way it gets food is a biological aspect of an organism's niche.
What is Biological niche?The term "niche" in ecology refers to the function an organism performs within a community.
The physical and environmental requirements (such as temperature or topography) and interactions with other species that a species must tolerate make up its niche (like predation or competition).
For instance, the tiny songbird from North America known as the Kirtland's warbler which is scarce, has an extremely constrained niche. It exclusively builds its nest amid young jack pine trees (Pinus banksiana), whose seeds need regular wildfires to germinate.
Therefore, The way it gets food is a biological aspect of an organism's niche.

Which molecules does a cell need from food to make these membrane
Answer: The organic molecules required for building cellular material and tissues must come from food. Carbohydrates or sugars are the primary source of organic carbons in the animal body. During digestion, digestible carbohydrates are ultimately broken down into glucose and used to provide energy through metabolic pathways.

What height in meters must the student climb in order to reach the top of the hill?
Answer: 256 or 300 sorry if i was incorrect
Explanation:
The student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.
What is the significance of the hill in the ecosystem?The hill is the highest point on Earth and plays an important role in ecosystems because it can provide a variety of different habitats for plants and animals as well as act as barriers that separate different ecosystems, such as the forest ecosystem present on one side of the hill from the grassland ecosystem present on the other side of the hill, and it is also a depositary of minerals and other resources.
Hence, the student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.

A man with blood type A, whose mother was type o, has a child with a woman that has type AB blood. Which blood
types are possible in their children?
Answer:
Ab a o
Explanation:
A man with blood type A, whose mother was type o, has a child with a woman that has type AB blood. Which blood
types are possible in their children AB, a, O.
What is ABO blood grouping ?The blood grouping can be defined by the presence of surface antigens in the red blood cell which are A and B. The gene present on the parent chromosome can determine the blood group.
Blood type A represents to the presence of gene A, and its genotypic expression can be A/A or A/O.
Type B blood group where genotype is represented as B/B or B/O, is due to the presence of a gene containing the B antigen.
AB blood group which is codominant- has one gene for A and another for B, with genotype A/B.
Blood type O is mainly characterized by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

If a gene is found only on the X chromosome and not the Y chromosome, it is said to be what?
codominant trait
sex-linked trait
incomplete dominance trait
Answer:
Sex-linked trait
Explanation:
When a gene is present on the X chromosome, but not on the Y chromosome, it is said to be X-linked. X-linked genes have different inheritance patterns than genes on non-sex chromosomes (autosomes). That's because these genes are present in different copy numbers in males and females.

As a star goes through this cycle their _____ changes.
A - luminosity
B - brightness
C - all of these
D - temperature
Answer:
option C. all of these.
Explanation:
The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.
What is a complete cycle of a particular star?The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.
The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.
The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.
The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.
Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.

In the middle of the night, you are awakened by hunger pains. You proceed to get up and go to the kitchen to have a couple of cookies and a glass of milk. Satisfied you go back to bed content. Explain in detail what tissues, organs, and organ systems are involved in completing that task. Be sure to include how the systems interact. The more detail the better! Start with getting up to get the food and include details on the steps in how the food gets digested.
. Explain in detail
Answer:
you would use your muscles from your legs and your body to get up from your bed and go to your fridge, your muscular system helps you up by being a structure for the muscles to apply force, you will use arm muscles for getting out cookies and milk. Then you will drink and eat your cookies and milk with your jaw muscle and send it down your esophagus to the intestines for the digestive system to break down your food. Then you will use your legs(muscles) to go back to your bed and sleep.
