Answer: The rock formed from cooling lava.
Explanation:Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.
The formula for calculating the density (p)=m/v
m:mass
v:volume
<u>Explanation:</u>
In the question above,given that
<u>mass of water (m)</u> =100 g
<u>Volume of water in a beaker (v)</u>=100 mL
<u>The Density of the water(p</u>)=m/v=100 g/100 mL= 1 g/mL
The answer is (B) 1 g/mL
Answer:
producer to decomposer
Explanation:
This is because in a food chain , energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun. Energy flow directly from the producer to the primary consumer which are heterotrophs that feed on plants. Energy flow from consumer to decomposer after the consumer died and it is decayed.
