Answer:
Option b. is correct
Explanation:
If hydronium ion concentration 
is given then pH is given by ![-log[H_3O^+]](https://tex.z-dn.net/?f=-log%5BH_3O%5E%2B%5D)
The hydronium ion refers to the hydrogen ion in aqueous solution.
A Tomato has A Proton Concentration Of 0.00006 M
Here, 0.00006 is equal to 6 × 
So,
pH is given by - log [6 × ]
Option b. is correct
Answer:
Ecology is defined as the scientific study of the complex interactions between organisms, and the environment of the earth. Ecologists study, and examine the features of biotic and abiotic factors of the environment.
Abiotic factors include non-living factors, the physical, and chemical attributes, for example light, water, temperature, and nutrients which helps to influence the abundance, and distribution of organisms.
Biotic factors include living factors, the other organisms which are part of a separate environment, similarly influence the abundance and distribution of life present on Earth.
