Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

An ecosystem is when plants and animals interact with each other in a specific area.
Fossil evidence has demonstrated that birds evolved from a group of small carnivorous dinosaurs. Scientists have hypothesized that some evolved into birds as they filled available niches. The most recent fossil discoveries have filled in many of the gaps in the evolution of birds from dinosaurs. Before the latest fossils were found, there were some scientists who questioned this idea that birds evolved from dinosaurs. In general, scientists constantly work to
Answer:
To find out the relationship of birds from dinosaur.
Explanation:
Scientists constantly work to find out the evolution of birds from dinosaur and relationship exist between them. Scientists do hard work in order to find out the evidences that shows and confirm the relationship of birds and dinosaur. These new discoveries provides evidences about the evolution and relationship between birds from dinosaur so we can conclude that scientists constantly find out the relationship between these two organisms.

Explanation:
Meiosis in males produces four identical sperm cells.
A. True
B. False
Answer:
B. False
Explanation:
Meiosis in males, not produces four identical sperm cells.
Meiosis is a type of cell division which involves the reduction in chromosomal content to half. The four daughter cells formed in meiosis are not identical. Thus, the given statement is false.
What is Meiosis?Meiosis is a type of cell division in which the number of chromosomes reduces by half than that present in the parent cell and produces four haploid gamete cells. This process is required to produce both male and female gametes- egg and sperm cells for sexual reproduction.
During the telophase II- last phase of meiosis, cell division is incomplete without another round of cytokinesis. Once the cytokinesis is complete there are four daughter cells, each with half a set of chromosomes (haploid) which are different due to the crossing over between chromatids.

Fungi live by
A. Making their own food.
B. Eating other organisms.
C. Sucking up nutrients made by other organisms.
Answer:
C
Explanation:
Fungi are heterotrophic.
Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. Most fungi are saprophytes, feeding on dead or decaying material.
Answer:
C. Sucking up nutrients made by other organisms.
Explanation:
Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem.
It could be other plants or animals where they get a great place to source their food.
During this time, the fungi kind of hibernates until they get a suitable and beneficial place they can transfer to.
Which Image shows the difference between the speed of molecules in hot and cold water

Explain what happens to an animal cell when it removed from an organism and placed into distilled water
Answer:
I think it has to do with osmosis
Explanation:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
When a cell is placed into distilled water, hypertonic solution takes place.
A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.

56:47 If you wanted to increase your muscular endurance, it would be important to participate in activities that __________. A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle B. decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract C. increase the number of muscles and decrease the size of the muscle cells D. decrease the length of the muscle and increase the thickness of the muscle
Answer:
The correct answer is - A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle.
Explanation:
Muscular endurance is the ability of a muscle to do some work or exert force continuously and rapidly for a period of time. To increase muscular endurance no heavy exercise required by including exercises that can help in increasing the size of the muscle cells and the amount of blood that is delivered to the muscle. The size of cells and delivering a high amount of blood helps in getting more oxygen and perform the metabolic activity more and generate more energy. So including the exercise rapidly and continuously will help in increasing the muscle cells.

a weather station predicts that warm, humid air will pass over much cooler land
Answer:
This happens when the air has a lot of moisture and when the temperature is low (because in this way the water in the air condenses). So if a weather station predicts that warm humid air will pass over much cooler land, the precaution must be to use healights and drive slowly because it will probably be dense fog.

❗️❗️EARTH SCIENCE CLASS ❗️❗️Climate factors are the things that established and have changed the Earths climate for billions of years. Which one does include changing the amount of CO2 in our atmosphere
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay, or release gas), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Which this also adds to the temperature increase around the world due to our atmosphere keeping all of this CO2.
