Which of the following is a true statement regarding phytoplankton?

they are the only cause of green ocean water
they are responsible for 80% of all global warming
they are the primary photosynthetic plants in the ocean
they are most commonly found near deep-sea thermal vents

True statement regarding phytoplankton is :

They are the primary photosynthetic plants in the ocean

Explanation:

Phytoplankton : It is made of two words :

"Phyto" means plants

"plankton" means drift .

Hence Phytoplankton  are plants that live in water .They are also known as microalgae and are similar to terrestrial plants because they also contain chlorophyll .

Most phytoplanktons are found on the surface of water so that they can get enough sunlight to prepare their food .

There are two kinds of phytoplankton

a) dinoflagellates (they have tail or flagella)

b) diatoms (they are shell like)

They provide food to many organism living in water . example : jelly fish , shrimps etc

Hence they balance the ecosystem

In this way they are primary producers in water -food chain

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
