- Just like the plants on the surface of the Earth, phytoplanktons also take in carbon dioxide & give out oxygen by absorbing sublight & conducting the process of photosynthesis.
They also form the base of the marine food-chain just like the terrestrial autotrophic plants.

- <u>Phytoplanktons are found to be largely located in the surface of oceans near to the coastlines, higher altitudes, or near to the equator. </u>

- This is because phytoplanktons need a lot of nutrients to survive & hence live near to the surface of oceans to get enough sunlight which helps in photosynthesis.

Answer:

approximately 200

Explanation:

From the question, we have

probability of red = 0.75

Probability of white = 0.25

We are required to find the probability of 6 red + 2 white plants offspring and after we do we multiply it by 640

We will solve this using the binomial theorem method

(a+b)⁸ = a⁸+8a⁷b+28a⁶b²+56a⁵b³+70a⁴b⁴+56a³b⁵+28a²b⁶+8a¹b⁷+b⁸

The required probability is 28a⁶b²

a = 0.75

b = 0.25

= 28 x 0.75⁶ x 0.25² x 640

= 28 x 0.178 x 0.0625 x 640

= 199.36

Which is approximately 200 crosses would be needed
