Answer:
Both statements are true
Explanation:
Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>
The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.
D. Lack of sunlight
Explanation:
In a forest, an example of a limiting factor is that lack of sunlight.
Limiting factors in an ecosystems are the that factors usually made up of environment resources that affects the growth and abundance of organisms in an ecosystem.
- Examples are sunlight, water, nutrient, air etc
- In a forest, sunlight is one of the limiting factors.
- Forest vegetation are stratified.
- The broad leaved canopy trees dominates and receives the bulk of the sunlight.
- The undergrowth beneath competes for the little sunlight that reaches below for their own use.
- Distributions of sunlight in an ecosystem affects the way in which vegetation are dispersed.
