This is the master gland of the endocrine system
What is the pituitary gland
100
This is the bottom level of a trophic pyramid
What is producers
100
This is the biggest level in the organization of life
What is biosphere
100
This is what is lost into the atmosphere through interactions of a community. Lucky for us, we continue to gain it through the sun.
What is energy.

This level consists of groups of different organisms interacting with one another
What is community

This is what antibodies do
What is mark the pathogen for death by a phagocyte

Sometimes a cell will receive a hormone that causes the continuation of a stimulus. For example when a baby is nursing, oxytocin is released, causing milk production. Milk production causes more nursing and the cycle continues. This cycle is known as what?
What is positive feedback.

This is the total amount of mass of living organisms in different trophic levels.
What is biomass
300
This is the ecological role of an organism, or how it interacts with its abiotic and biotic factors of its environment
What is niche
300
This is the amount of energy lost between two trophic levels.
What is 90%

This is the process where water turns into water vapor and goes into the atmosphere
What is evaporation

These are the cells of the cell-mediated immune system. This is what they do for the body.
What is cytotoxic t-cell (kill infected cells), helper t-cells activate cell-mediated and humoral systems, memory t-cells for future attacks.

This is how the endocrine system is different than the nervous system
What is slower-acting, longer-lasting, gradual changes in the body
500
These are examples of biotic factors
What is other organisms
