1. Explain how the energy flows within living systems. Include the
following concepts:
• 10% Energy Transfer
• Food Web
• Food chain
(3 points)
2. Explain how energy is transformed through the process of
photosynthesis. (2 points)
Answer:
Explanation:
energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. Energy may be lost in living systems as it flows through them.
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
10% energy transfer is the law of energy transfer in which about 10% of the energy is transferred to the next trophic level in an ecosystem.
What is the energy flow in an ecosystem?Energy flow is the flow of energy which occurs through the living things within an ecosystem. All the living organisms in an ecosystem can be organized into different groups such as producers and consumers, and the producers and consumers can be further organized into a proper food chain. Each level within a food chain is called as trophic level.
1. 10% energy transfer is the law which states that 10% of the total energy is transferred to the next trophic level and 90% is lost into the atmosphere.
Food web is a network of interlinked food chains. In this different organisms are produce at each trophic level which provides the organism with different options for their food.
Food chain is a linear network of different organisms at different trophic levels in an ecosystem.
2. Photosynthesis is the process of energy transformation in which light energy in the form of sunlight is transformed into chemical energy in the form of chemical bonds present in the carbohydrate molecules.

Answer:
D
B
A
A
Explanation:
I hope this helps :)
Answer:
1 - D
2 - B
3 - A
4 - A
Explanation:
Hello There!
D=Distance
T=Time
S=Speed
For the first one we are given the speed and the time and we need to find the distance
To do so we multiply the two together( the two meaning the speed and the time)
They run 20 m per second and
if they run for 40 second
(20*40=800)
they will run for a total of 800m therefore the answer to the first one is D
for the second one we are given the distance and the time and we need to find the speed.
Looking at the formula chart we can find the speed by dividing the distance over the time
so speed = 80/5
80/5=16 so the speed is 16m/s (B)
For the third one we are given the distance and the time and we need to find the speed
Once again we can find the speed by dividing the distance over time
20/5=4 so the bunny hops 4m/s
For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance
another way we can find the time is by dividing the given speed by the distance
so time = 1500/250
1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m

If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?
Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.
Explanation:
In which atmospheric layers does temperature decrease with altitude?

In 1-2 sentences, explain why mutations can be beneficial to an organism.
Answer:
Some mutations can change genetic variation in a way where an organism can adapt to the surrounding environment. Mutations created gills, which allow fish to breath underwater. Mutations allowed giraffes to reach leaves higher up on trees so they can get food. Mutations also allowed humans to be able to adapt to any environment and situation and continue growing.
Explanation: Brainliest is always appreciated
Mutations are random changes in the DNA sequence of an organism's genome. Mutations can be beneficial to an organism because they can lead to genetic variation, which can allow for natural selection to occur.
What is mutation?Mutation is a process that refers to a change in the genetic material (DNA) of an organism. The genetic material carries the information that determines an organism's characteristics and traits, like eye color, hair color, or susceptibility to certain diseases. Mutations can happen naturally, or they can be induced by various factors such as exposure to radiation, chemicals, or viruses.
Mutations can affect a single base pair of DNA, a larger segment of DNA, or an entire chromosome. They can be classified in many ways, but one of the most common ways is by their effect on the genetic material.

Obesity can lead to high blood pressure.
Childhood obesity is a severe public health concern that is spreading across the country. Body mass index (BMI) at or above the 95th percentile for kids of the same age and sex is what is referred to as having it. The claims are all accurate.
Obesity can raise the chance of having high blood pressure because it alters the body in ways that enhance that risk. This includes increased blood fat levels, hormonal changes, and an increase in the creation of proteins that can narrow the blood arteries.
