High-altitude environments present a number of physiological challenges for endothermic animals, as they are characterized by a lower partial pressure of oxygen (<span>) and lower ambient temperatures compared to low-altitude environments at similar latitudes. The reduced </span><span> at high altitude results in reduced oxygen loading in the lungs such that the blood may not carry a sufficient supply of oxygen to the cells of respiring tissues (</span>Bencowitz et al. 1982<span>; </span>Bouverot 1985<span>; </span>Turek et al. 1973<span>). This reduced level of tissue oxygenation can impose severe constraints on aerobic metabolism and may therefore influence an animal's food requirements, water requirements, the capacity for sustained locomotor activity, and the capacity for internal heat production.

A because if you look it up phytoplankton does uses photosynthesis to produce food.
<span>B. How organisms could change. He has a wide study of animals and their behavioral changes to achieve perfection. From simple actions, they learn more skills. He explained the idea of use vs disuse and traits can be inherited. This contributed to the theory of evolution.</span>
Answer:
Male cones are a lot smaller than female cones and their scales aren't as open. Each scale in a male cone contains the pollen that can spread to a female cone to make a seed.
Explanation:
I don't know what you are asking but that is my answer.....be more specific.
