Biology Questions and Answers
Biodiversity
- What is biodiversity?
Biological diversity is the variety of
species of ecosystem.living b In ecosystemseings of an which ar (^) e
more biodiverse, like tropical forests, a
great variety oand animals live; in ecosystemsf plants, microorga lessnisms

- How does biological
diversity relate to the
characteristics of the abiotic
factors of an ecosystem?
The availability of abiotic factors like
light, moisture, carbon dioxide, mormineral salts,e or less con heat andditions (^)

light, and plants also need mineral salts,
carbon dioxide and adequatetemperature for their cells to w (^) ork. In

- How does the vegetal
stratification of an ecosystem
influence the biological
diversity?
The vegetal stratification of an
ecosystem,Amazon Rainfor like the strata of theest, creates vertical (^)
