Answer:
Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:
- Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
- Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.
your answer is going to be a.true hun:)
Low-density lipoproteins (LDL) are the principal transport vehicle for cholesterol in the blood.
The body needs cholesterol, a waxy, fatty molecule, in the proper proportions for overall health. High blood cholesterol is a disorder that can result from unfavorable cholesterol levels. Low-density lipoprotein (LDL), also known as "bad" cholesterol, is the type of lipoprotein that carries cholesterol in your blood.
Cholesterol is primarily brought on by consuming fatty foods, failing to exercise regularly, being overweight, smoking, and using alcohol. Moreover, it can run in families. By consuming a healthy diet and increasing your physical activity, you can lower your cholesterol. Some folks also require medication. The majority of the cholesterol in your body is LDL (low-density lipoprotein), also referred to as "bad" cholesterol. Your risk of heart disease and stroke increases if your LDL cholesterol levels are high.

Answer:
The structure that prevents backflow of blood into the left atrium is the mitral valve.
The vessel that carries oxygen-rich blood to tissues is the aorta.
The capillaries receiving blood flow from the left side of the heart are the Systemic capillaries.
The structure that is located anatomically between the aorta and the left ventricle is the Aortic semilunar valve.
Explanation:
The left atrium receives oxygen-rich blood from the pulmonary vein and passes it to the left ventricle. The back-flow of blood from the left ventricle into the left atrium is prevented by mitral which is a bicuspid valve. The vessel that carries oxygen-rich blood to tissues is the aorta.
Aorta receives oxygen-rich blood from the left ventricle and pumps it into its branches to deliver the blood to the body tissues. Systemic capillaries are the blood vessels that obtain the oxygen-rich blood from the left ventricle through the aorta. Systemic capillaries serve as the site for the exchange of gases and nutrients.
The aortic semilunar valve is located Aortic semilunar valve is the half-moon shape valve present between the left ventricle and aorta to prevent the black flow of blood to the left ventricle.
Oof I don't think ppl like that (ŏ_ŏ)
