<h2>(A) is the correct option </h2>
Explanation:
- An organism is part of a community is correct,where species interaction occurs between different organisms
- A community is part of population is the incorrect statement because a community includes group of population of two or more different species
- An ecosystem is made up of only organisms is the incorrect statement because ecosystem is the community of both living and non living components of the environment and how they interact with each other
- A biome is the biotic part of an ecosystem is incorrect because biome includes the community of both plants and animals occupying a large habitat
Answer:
a gas produced during photosynthesis
Explanation:
during photosynthesis plants use carbon dioxide, water and sunlight to make sugar (glucose) and a waste product, oxygen gas.
the equation of this process can be:
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
carbon dioxide + water + light → glucose + oxygen
Answer:
Decomposers and scavengers break down dead plants and animals. They also break down the waste of other organisms. Decomposers are very important for any ecosystem because if they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
Explanation:
Answer:
Greenhouse gases are good because they keep the Earth warm. They trap the heat energy that is radiated from the Earth in the atmosphere. Without greenhouse gases, the Earth would have an average yearly temperature of 0 degrees Celsius.
The answer is B. This is called genetic shift. The pups with
advantageous traits are able to survive until the age of reproduction hence able
to pass their genes to the next generation. Few and fewer pups with disadvantageous
traits will get to reproduce hence the allelic frequencies of the shark population
will shift in favour of increased hunting efficiency.
