What is a feeding relationship in an ecosystem?A feeding relationship in an ecosystem is a relationship that shows the interaction between organisms present in an ecosystem.
A feeding relationship usually depends on the primary producer, and then the primary consumers, secondary consumers, and tertiary consumers.
The tertiary consumers occupy the highest level in a feeding relarionship.
A feeding relationship is also known as a food chain.
In a food chain, the primary consumer depends on the primary producer; the secondary consumer depends on the primary consumer, and the tertiary consumer depends on the secondary consumer.
Therefore, an increase in the number of organisms in a higher level in the food chain will result in a decrease in the number of organisms at a lower level.
Between a beaver and a wolf, the wolf eats the beaver and thus, occupies a higher level in the food chain.

Explanation:
Round seeds are the dominant phenotype, according to this observation. Given that round seeds are dominant, wrinkle seeds are the recessive trait. As a result, a cross of a round heterozygous recessive with a wrinkled homozygous recessive will result in an F1 generation with 50% round seeds and 50% wrinkle seeds. Round seeds would be heterozygous as well.
Wildflowers are plants that grow on the forest floor. During a study, a scientist observed that wildflowers began to bloom before the leaves appeared on the tall trees above them and stopped blooming once the trees were full of broad leaves which blocked the sunlight.
Evaluate this observation and explain a limiting factor this is affecting the wildflowers on the forest floor.
Answers
The leaves on the tree are blocking sunlight from reaching the flowers. This is stopping the flowers from getting what they need for photosynthesis, and they are not blooming because that requires photosynthesis.
Answer:
sunlight
Explanation:
Plants need sunlight as an essential nutrient like nutrients from the soil and water that are needed to photosynthesize. when they are at the ground the leaves at the top cover the sunlight which limit the growth of the plants because they are not able to photosynthesize to their full potential
Drag into the correct order, starting with deoxygenated blood entering the right atrium (1 = first) This deoxygenated blood is pumped out of the heart and towards the lungs by the right ventricle 1 At the lungs the deoxygenated blood exchanges carbon dioxide for oxygen, becoming Oxygenated Oxigenated blood returns to the left atrum of the heart Deoxygenated blood from the body enters the right otrum of the heart The blood becomes deoxygenated and returns to the heart The oxygenated blood gives its oxygen to body cells in exchange for carbon dioxide
Answers
To answer this we must remember quickly how the blood flows in the heart. Blood enters through the superior vena cava to the right atrium then through the tricuspid valve passes to the right ventricle, the blood flows then to the pulmonary valve and the pulmonary artery directly to the lungs where is oxygenated, later returns through the pulmonary vein and mitral valve, to the left ventricle where is directed through the aortic valve into the aorta and into the rest of the body. Therefore the order is as follows:
1.- Deoxygenated blood from the body enters the right atrium of the heart
2.-This deoxygenated blood is pumped out of the heart and towards the lungs by the right ventricle
3.- In the lungs the deoxygenated blood exchanges carbon dioxide for oxygen, becoming Oxygenated
4.- Oxygenated blood returns to the left atrium of the heart
5.-The oxygenated blood gives its oxygen to body cells in exchange for carbon dioxide
6.- The blood becomes deoxygenated and returns to the heart
Note: there is a step missing after point 4 as blood goes to the left ventricle before leaving the heart.

What is the carrying capacity of an environment for a population with rmax = 3, that exhibits no population growth when N = 3000?
Answers
Let's define what our logistical growth formula is:
[tex]\frac{dN}{dt}=r_{max}N\bigg(\frac{K-N}{N}\bigg)[/tex][tex]\frac{dN}{dt}=r_{max}N\bigg(\frac{K-N}{N}\bigg)[/tex]Where r (max) is the max per capita growth rate of population, N is the population size, and K is the carrying capacity.
If we are given that r (max) is equal to 3 and that the given population exhibits no growth when N = 3000, we can find what the carrying capacity is by substituting into our formula:
[tex]\frac{dN}{dt}=3(3000)\bigg(\frac{K-3000}{K}\bigg)[/tex]Let's simplify this a little more:
[tex]\frac{dN}{dt}=9000\bigg(\frac{K-3000}{K}\bigg)[/tex]If we are trying to find the carrying capacity, then recall that the amount of change in the population with respect to time (dN/dt) must equal 0. Therefore, we can set our derivative to be equal to 0 and find the value of K:
[tex]0=9000\bigg(\frac{K-3000}{K}\bigg)[/tex]Interpreting this, it means that whatever the growth is 0, it is dependent on the value K carrying capacity. When we solve this out, we can obtain an answer for the carrying capacity:
[tex]K=3000[/tex]∴ the carrying capacity K of this environment is equal to 3000 organisms.

A satellite orbiting Earth at an orbital radius r has a velocity v. Which represents the velocity if the satellite is moved to an orbital radius of 5r?(1 point)
Answers
For satellites, the centripetal force for rotation is provided by the gravitational force acting on them.
What is force?In general language we can say that push or pull is called force.
According to newton second law of motion force is rate change of momentum it means
F= d/dt×(mxv)
Where m is mass and v is velocity
But in general case mass is constant.
So, Force
F= mxd/dt×(v)
Since we know that rate change of velocity is acceleration.
Then we can say that
F= mass x acceleration
S.I unit of force is Newton
1 Newton = 1kg×m/sec^2.
Force and acceleration is a physical quantity which have both i.e magnitude and direct it means both are vector quantity.
