Photosynthetic organisms like grass are able to make all of their organic matter from organic molecules in the soil. use water they take in through their leaves as a final electron acceptor. change the light energy from sunlight into sugars use substances in the air as a major source of carbon.

Use substances in the air as a major source of carbon.

Explanation:

Photosynthesis is the process wherein green plants fix the atmospheric carbon dioxide (CO2) into glucose in the presence of sunlight. The process uses CO2 as a source of carbon, sunlight as a source of energy and water molecule as a source of electrons to drive ATP and NADPH synthesis. Grasses are also photosynthetic organisms that can make organic nutrients by the process of photosynthesis. Stomata present in the leaves of grasses allow the atmospheric CO2 to enter the mesophyll cells followed by sunlight driven fixing of CO2 into glucose.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
