Answer:
it is only the black cra ppie.
Explanation:
the whirl gig beetle, water cricket are secondary consumers and the copepod is a primary consumer.
3) decrease
Without the green house effect, earth would be like a solid ball of ice and rock.
Life as we know it wouldn't exist without greenhouse gases.
The temperature would drop below 0° Fahrenheit!
1. Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
Pigments inside the photosystems absorb light energy. Energy is transferred to reaction center, where electron is boosted at higher level. Electron is then passed to an acceptor molecule, replaced with an electron from H2O. and O2 is released.
2. Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space
Electron releases energy because it goes from a higher to a lower energy level.
3. The concentration of hydrogen ions in the thylakoid space increase
Released energy of electrons drives pumping of hydrogen ions from the stroma into the thylakoid interior, building a proton gradient.
4. Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
The only way for hydrogen ions to move down the gradient is through ATP synthase.
5. ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
ATP synthase is an enzyme that use proton gradient to make ATP from ADP and Pi.
Answer:
hummingbirds can only survive in an area that meets their basic needs for food, including both insects and abundant nectar, as well as fresh water, shelter, and safe nesting sites.
Explanation:
Answer:
See the answer below
Explanation:
<em>Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level. </em>
Obligate bacteria such as <em>Clostridium botulinum </em>obtain their energy through <u>anaerobic respiration processes such as fermentation and anaerobic respiration.</u> During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.
