The abiotic factors in salt marshes include:
1. High, variable salinity
2. Low oxygen levels
3. Turbidity
4. Varying temperature
5. Sulphide toxicity
Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.
Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes and therefore salt marshes are generally poor in species.
It is called The Cell Theory.
The answer is c. anything made by humans, as opposed to things made by nature.
Answer:
During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:
transported to the growing parts of the plant for use in respiration
transformed into cellulose, proteins and oils
turned into starch for storage
Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.
Binary fission, hope this helped:)
