Ecology Unit Review 1.) Define ecology.
Ecology is the study of the relationships between living organisms. 2.) List the correct order, from smallest to largest, of levels of organization for ecology.
Organism, species, population, community, ecosystem 3.) Describe the different levels of organization for ecology.
An organism is an individual living thing. A species is a group of organisms that are able to produce fertile offspring and share common genes. 4.) Describe the different sources of energy for an ecosystem. (sun, organic matter)
The sun essentially provides energy for the entire ecosystem because it helps producers produce, and the consumers eat the producers. …show more content…
Plants and algae are autotrophs, and tigers and humans are heterotrophs. 6.) Describe the different types of consumers.
Herbivores eat plants. Carnivores eat meat. Omnivores eat plants and meat. Decomposers, such as fungi and bacteria, break down dead organisms for food.
They return nutrients to the soil. 7.) Describe how energy flows through an ecosystem.
Autotrophs get energy to make food through the sun, and the heterotrophs get their energy from consuming the autotrophs; they are indirectly getting their energy from the sun, because that is how the autotrophs grew. With every level, 90 percent of energy is lost. 8.) Describe the difference between a food chain and a food web.
A food chain is a sequence in which energy is transferred from one organism to the next as each organism eats each other. A food web is a more accurate illustration of what organisms eat. It shows many of the feeding relationships. 9.) Describe a food chain in which you are a member.
I am the tertiary member in the chain; I eat the cow that eats the grass. 10.) Describe how trophic levels differ from one another on an ecological pyramid.
One higher than another has 10 times less energy than the one below …show more content…
Literal, design, and expressive qualities 2.) When examining an artwork, for what kinds of questions does a critic seek answers?
A critic seeks answers for what is seen in the artwork, how it is designed, what it means, and if it’s a successful work of art. 3.) How did the lack of footprints in the sand around the gypsy influence Robert’s interpretation of The Sleeping Gypsy?
With the lack of footprints in this painting, Robert interpreted it as more of a dream than reality. 4.) Why is judgment such an important step in the art of criticism process?
Judgment is important to the art criticism process because the theories that the critics favor help identify the different aesthetic qualities found in the artwork. 5.) Why is no single theory of art adequate when examining and judging different works of art?
No single art theory is enough for an art piece because in all of them literal, design, or expressive qualities are expressed. 6.) Where do critics turn to find out more about a work after they have examined it using the art criticism operations?
They turn to
