Is a post oak tree is a autotrophic or heterotrophic

1 answer:

6 0

All plants are autotrophic.

Autotrophic means he doesn't need another living thing to live(for eating) but that he makes his own food (photosynthesis). (auto means itself).

Heterotrophic means he needs others to keep on living. Like animals. All animals need to eat and can't make their own food with only sunlight, CO2 and water. They need food, which may be plants or other animals. That depends on the animal.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of

WARRIOR [948]

Answer:

The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.

Explanation: First we must talk about 3 facts:

1) Prism scatters the white light into different wavelengths.

2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.

6CO2 + 6H2O → C6H12O6 + 6O2

3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.

So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (see figure). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).

How do solar pants turn sunlight into electricity? What steps are involved?

MrMuchimi

Every solar panel contains photovoltaic (PV) cells. PV cells take light, or photons, and turn the light into electricity. When sunlight hits the solar panel, PV cells get to work by producing direct current (DC) electricity. ... That's where the other pieces of solar energy equipment come into the picture.

Why do biologists classify

ohaa [14]

Answer: It is because it makes it more efficient to study organisms.

Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
