Biology; Chapter 2; Variety Of Life, Adaption And Competiton Flashcards
Name the common system for naming organisms.
The BINOMIAL system for naming organisms.
State one difference between plants and animals.
Plant cells have cell walls whereas animal cells do not.
Name the 5 categories for naming organisms.
Kingdom, Phylum, Class, Order, Family, Genus, Species.
What 2 categories are used to name the organisms
The GENUS and the SPECIES.
The closer the relationship….
The more similar the DNA
Why are the scientific names used all around the world?
This avoids confusion when referring to a certain species across different languages.
Why do organisms adapt and develop structural behavioural adaptions?
Organisms adapt and develop structural and behavioural adaptions that help them survive in their environment.
What do all living things need to survive?
All living things need energy to survive.
How does energy enter ecosystems?
Energy enters ecosystems in the form of sunlight, which can be used directly by plants.
How do animals get their energy?
Animals get their energy by consuming other living organisms (either plants or animals).
Besides energy, what is also needed for the life process?
A variety of chemical ‘Raw Materials’ are also needed for the life process.
Organisms of the same species will …
Always compete with each other for sunlight, food or other raw materials, because their needs will be the same.
Competition doesn’t only occur between organisms in the same species ….
Competition also occurs between different species if they have similar needs.
A species may die out if …
A species cannot compete successfully for a resource in short supply.
