How do energy and matter move in ecosystems?

Biology
1 answer:
Delvig [45]2 years ago
3 0

Answer:

Energy flows in one direction, and matter cycles through the environment.

Explanation:

• Energy passes on from the producers (plants) up to the final consumer who absorbs it all. When final consumer dies, also energy collapses. So, more energy will be required hence a new cycle begins.

• Matter such as nutrients are taken up from primary consumers to the final consumer. When final consumer dies, its nutrients decompose are reused by the producers hence cycle repeats again.

#2: Fact

#3: Bias

# 4: Bias

#5: Fact

#6: Fact

BIAS: Tomatoes taste better when fish

DNA is inserted into them. Cereal is more

filling when cow DNA is inserted into it.

Testing GMO on rats and cockroaches

is ethically wrong.

FACT: Genes from different species can

be spliced into an organism to produce

desired traits. GMO crops can be

designed to grow in environments where

the natural species can't grow. The genes

from GMO plants can spread to natural

species if they successfully mate.
