Answer:
Ecological succession refers to the changes taken place in a forest over a particular period of time.
Succession is usually influenced by environmental factors such as water regimes, soil type, climate, vegetation history, and invasive species.
Humans interventions affect all of the above-mentioned factors.
Human activities such as fragmentation of forests, clearing of forests for agricultural practices, construction of dams, civilization, logging et cetera drastically reduce the biodiversity of a forest.
This reduction of biodiversity forms the foundation for a secondary succession of a forest.
ummm I'm so sorry but I don't know the answer to this one. maybe try looking it up? I'm sorry again.
Answer:
a.) Biomass is the total mass of biological material, both living and recently dead, in a defined area.
b.) The Sun's light is the original source of these energy forms. Both are formed into original material by photosynthesis, sunlight combining carbon dioxide and water into plant matter.
c.) Coal, oil and natural gas (or methane).
d.) Non-renewable resources cannot be naturally replaced in a small enough timescale for us to have an unlimited supply. When we have run out, it will take natural processes millions of years to form them again.
Answer: Option D
Explanation:
In case, tiger has not been killed by the hunter it could have produced more fertile offspring in his lifetime.
The tiger which is most fit is the one who can produce the maximum number of fertile offspring when it is alive.
No matter when the tiger is being killed by the hunter it is giving birth to 9 fertile offspring during his life so this tiger is the fittest tiger.
Hence, the correct answer is option D
Mosses and Ferns are seedless, thus they reproduce by releasing spores.
