Inhaling oxygen and exhaling carbon
Answer:
1. Plants utilize some of the incoming energy derived from photosynthesis for their own self-maintenance.
3. Plants and algae carry out both photosynthesis and cellular respiration.
5. Plants, algae, and cyanobacteria utilize light energy from the sun into their own biomass.
Explanation:
The gross primary productivity (GPP) of an ecosystem represents the rate at which the solar energy is captured during photosynthesis in a given period. Producers (plants, algae and cyanobacteria) perform cellular respiration to provide energy for their life processes. Cellular respiration consumes part of the total photosynthetic output. The energy available in tissues of producers after cellular respiration is called net primary productivity (NPP).
Therefore, NPP is the amount of biomass or the energy stored in the tissues of the producers for growth after cellular respiration for their normal daily activities and self-maintenance. So, NPP is always less than GPP.
Answer: Option 'd' is correct.
Explanation:
Since we have given that
Number of fish caught = 100
Number of tagged fish in catch = 24
So, total number of the fish in the pond is given by
Number of fish caught + Number of tagged fish in catch
=100 +24
= 124
So, the best estimate to find the number of fish in the pond is 124.
Hence, Option 'd' is correct.
Answer:
Electron transport chain
Explanation:
In all eukaryotes electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
Electron transport chain consists of protein complexes that transfer electrons from donors to acceptors via redox reactions. As a result of electron transport, protons (H+ ions) are pumped across a membrane and electrochemical proton gradient is formed. Proton gradiend is used for the ATP synthesis.
