in an aquatic ecosystem, the algae and phytoplankton are responsible for primary productivity. All BUT ONE factor usually influences the primary productivity of a marine ecosystem. That is a)water salinity b)light intensity c)water temperature d)available nutrients

Answers

Answer 1

Answer:

Answer: Light intensity

Explanation:

The total amount of nutrient( organic material) which is left after respiration, in order to support the other levels of the food chain is known as the net primary productivity.

More than 90% of the producers are the pytoplanktons that performs the process of photosynthesis.

The intensity of light falling on the water surface affects the rate of primary productivity.

Answer 2

Answer: C

These are two metamorphic rocks. Which statement about the rocks is accurate? The rock on the right is foliated. The rock on the left formed from granite. The rock on the left is formed from cooled magma. The rock on the right has randomly arranged grains.

Answers

Answer:

The rock on the right is foliated

Explanation:

There are three types of rocks. Metamorphic, igneus and sedimentary.

Igneus rocks are formed from magma that cooled in one point of earth history, so non of the metamorphic rocks is formed from cooled magma.

Sedimentary rocks are formed from varios sediments or grains that after processes of pression or temperature compact together. So, metamorphic rocks are not formed from randomly arranged grains

Metamorphic rocks are rocks that change their shape for a phisical reason. One common way to find metamorphic rocks is foliated, this means that the rock has layers. Like a book, with different sheets.

When a metamorphic rock is formed from granite, the pattern is foliated, with layers and the form of the rock is usually banded, this rock is called Gneiss. The left image is not layered.

The right image is layered like sheets, this is the only option that has no counter arguments
