fill in the blank

1. the scientific study of interactions determining the __ and __ of organisms is called ecology.
2. the __ includes all living organisms, while the __ includes non - living factors.
3. the ____ is made up of gases surrounding the earth from its surface to space.

multiple choice

1. ecology is the study of:

a) weather patterns and climate zones
b) the relationship between an organism and its environment
c) geological formations of the earth
d) chemical properties of ecosystems

1. which of the following is not an ecological level?

a) biosphere
b) ecosystem
c) population
d) evolution

1. which level of ecological organization includes only one species living in a specific area at a specific time?

a) population
b) community
c) ecosystem
d) biosphere
short answer

1. what 3 parts make up the biosphere?
2. name two types of grassland biomes.

diagram

1. label the diagram of the ecological levels below (biosphere, ecosystem, community, population, organism).

ecological levels diagram:

Explanation:

1. Ecology studies the interactions that determine the distribution and abundance of organisms. The biotic factors are living organisms and abiotic factors are non - living.
2. The biosphere includes all living organisms from Earth's surface to space. The atmosphere is the gas - filled layer around the Earth.
3. Ecology focuses on the relationship between an organism and its environment.
4. Evolution is a biological process not an ecological level.
5. A population is a group of one species in a specific area at a specific time.
6. The biosphere is made up of the atmosphere, hydrosphere, and lithosphere.
7. Two types of grassland biomes are savanna and temperate grassland.
8. For labeling the diagram, the organism is an individual living thing, population is a group of the same species, community is multiple species in an area, ecosystem includes biotic and abiotic factors, and biosphere is the global sum of all ecosystems.

Answer:

1. distribution, abundance; biotic factors, abiotic factors
2. biosphere; atmosphere
3. B. The relationship between an organism and its environment
4. D. Evolution
5. A. Population
6. The atmosphere, hydrosphere, and lithosphere
7. Savanna, temperate grassland
8. (No diagram provided for actual labeling, but conceptually: organism is an individual; population is a group of the same species; community is multiple species; ecosystem is biotic + abiotic; biosphere is global)
