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.
State TWO characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants . Explain how EACH characteristic makes the respiratory surface suitable for gaseous exchange .
Answer:
Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Respiratory surfaces in both human beings and plants have several characteristics that are peculiar and similar to each other. There are some requirements to be met for gaseous exchange to occur.
Two characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants include ---
1. Respiratory surface must be thin and allow for rapid diffusion.
2. These surfaces must be in contact with air or fluid.
Respiratory surfaces in plant living cells in the stem are organized in thin layers close to the surface.Their loose packing ensures air spaces where they are in close contact with the airflow either in or out. In humans, the respiratory surface is thin allowing for rapid diffusion of oxygen in and CO₂ out. They are also always in contact with the bloodLearn more: https://brainly.com/question/9128660

why is it important to keep pollution out of the nearest system river?
Dirt
Dirt is a big cause of pollution in our rivers and streams. Rain washes dirt into streams and rivers. Dirt can smother fish and other animals that live in the water. If plants can't get enough sunlight because the water is murky, they die.
Most of the dirt washing into lakes and streams comes from exposed earth. This exposed earth includes plowed fields, construction sites, and areas that have been logged or mined. Some of the dirt polluting streams comes from the stream banks.
The solution is to stop the dirt from getting into the stream in the first place by disturbing the land as little as possible. Farmers and construction workers are using new methods to reduce the amount of earth they disturb.
Bacteria
water pollution
Bacteria are also a big water quality problem. Not all bacteria are harmful, but germs and viruses that can make you sick might be in the water. Bacteria can come from combined sewers after rainstorms and runoff of animal waste from farms, pets, and wildlife.
Sewage systems can be improved to keep untreated sewage from overflowing. Farmers are developing better ways to manage livestock manure. Dog owners are picking up after their pets.
Nutrients
Nutrients are element needed for animal or plants to grow. The two most common nutrients found in water are nitrogen and phosphorus. They cause algae to grow and can turn the water green.
The major sources of nutrients are runoff of fertilizers from farms and lawns, animal waste, sewage treatment plants, and septic systems.
Farmers, homeowners, cities, and towns are all working to reduce the amount of nutrients that get into rivers and streams.
Ponds, Lakes, and the Sea
Water in streams and rivers flows into ponds, lakes, and the sea. Keeping streams and rivers clean helps keep all the water downstream clean, too.

Explanation:
Why is it difficult to fossilize large animals?
There are not enough rocks to cover large animals.
Large animals are harder to cover due to many environmental factors.
Large animals are usually decomposed faster than smaller animals.
Fossilization requires very specific environmental conditions.
Answer:
The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.

Do living things go through mitosis? Justify your answer
Answer:
Yes
Explanation:
mitosis is how more cells are created that are genetically identical to the parent cell. it's essential to growth and repair
All living organisms are able to reproduce and produce offspring, where as eukaryotic organisms that includes aquatic plants and algae, which proliferate through the process of mitosis. Mitosis is the process in which a cell divides into two cells.
What is Mitosis?Mitosis is defined as the process of cell division in which chromosomes are duplicated and equally distributed into two daughter cells where each daughter cell has the same number of chromosomes as the parent cell, i.e. diploid. Hence, mitosis is known as equivalent division.
The mitosis process, which produces two identical nuclei/daughter cells, has four phases: prophase, metaphase, anaphase, telephase. Mitosis in the cell cycle is preceded by the G2 phase where metabolic changes assemble the cytoplasmic materials needed for mitosis and cytokinesis and the metabolic changes that occur after the G1 phase prepare the cell for division.
Thus, all living organisms are able to reproduce and produce offspring, where as eukaryotic organisms that includes aquatic plants and algae
