Characteristics of Life
List 3 characteristics that all living organisms must have?
1- Be composed of one (unicellular) or more cells (multicellular)
2- Contain either DNA or RNA as their genetic material- Be capable of growth (develop and becoming larger)
3- Be capable of reproduction (producing offspring)- 4- Demonstrate the ability to respond to outside stimuli
5- As a population, be able to adapt to the environment and evolve
6- Have a metabolism, meaning both consume energy and produce waste
7- Maintain homeostasis
8-be capable of growth
What is the broadest level of ecological organization?
biosphere
Define ecology.
Ecology is the study of relationships –- Between two organisms- Between an organism and its environment
Name two characteristics of a biome.
Climate (amount of sun, temp, precipitation.)
Types of animals
Types of plants
Abiotic factors (landscape)
Describe a food chain from this picture.
Answers may vary.
Phytoplankton --> zooplankton --> kelp bass
Differentiate between sexual and asexual reproduction.
Sexual reproduction = 2 parents; offspring are different from each other.
Asexual reproduction = 1 parent; offspring are identical to parent
Name the level of ecological organization that includes all the organisms of the same species in a given area.
population
What is the definition of "biodiversity"?
Describe the climate of a tropical rainforest biome.
High temps, lots of precipitation
Name the two decomposers in this picture.
sea cucumber and bat star
Describe the role of metabolism in living organisms.
To break food down and build new molecules
List the levels of ecological organization from broadest to most specific.
Biosphere, biome, ecosystem, community, population, organism
What does "binomial nomenclature" refer to?
2-name naming system that names organisms after their two most specific classification levels: Genus species
What adaptations might organisms have in a desert biome?
Small leaves, thick waxy layer on leaves, camouflage, deep roots, water conservation, can vary metabolic rate.
Describe the community in this picture.
All of the different species in the picture (whales, fish, otters, starfish, phytoplankton)
Provide an example of a stimulus and a corresponding response.
2- You pull your hand back after touching something hot.
What is a community in ecological terms?
Different populations living together in the same area.
Define "cladogram" and its purpose.
Tool used for identifying organisms based on their characteristics
Name 3 characteristics of a climate.
temperature, precipitation, amount of sunlight.
List 3 biotic and 3 abiotic factors in this picture.
Biotic: any living organism
Abiotic: temperature, aquatic, amount of sunlight, wind, current, rocks

6- Have a metabolism, meaning both consume energy and produce waste
7- Maintain homeostasis
8-be capable of growth
Define an ecosystem.
All the relationships between the biotic and abiotic factors in a given area.
What is a climatograph, and what information does it convey?
Temperature and Precipitation over a period of time for a specific area.
Name four characteristics of a biome.
Climate (amount of sun, temp, precipitation.)
Types of animals
Types of plants
Abiotic factors (landscape)
What biome do you think this is?
