There are 8 Properties of Life we've discussed, two are missing from the list below. Which are they?
Chemical uniqueness - all organisms are carbon based, and made up of the same organic compounds (carbohydrates, lipids, proteins, and nucleic acids)
Hierarchical organization – the system of life is organized in hierarchies, and each level has its emergent property.
Reproduction – all life produce offspring. Methods of reproduction are grouped into two main types: sexual and asexual.
Growth and development – characteristic changes that organisms undergo from origin to adult (i.e. size, shape, differentiation)
Metabolism (energy processing) – organisms carry out chemical transformation of energy to perform work, maintain themselves (homeostasis) and reproduce
Homeostasis (regulation) – life systems have the ability to sustain their internal environment and keep it relatively constant using morphological or behavioral (or both) traits

Name these 6 factors for extinction based on the examples
1. #1 reason for species decline; deforestation, wetland draining, coral reefs due to ocean acidification, grass lands lost to agriculture
2. #2 greatest reason for species decline; Emerald Ash Borer and Asian Longhorn Beetle (forest insects that destroy trees), feral cats
3. Direct human cause, often due to commercial markets; passenger pigeon, Stellar’s Sea Cow, Mahogany, cod, tuna……
4. Decrease in whales leads to increase in plankton, which led to increase in pollack and decreases in herring and perch, which led to decreases in seals and sea lion, which led orcas to eat sea otters, which caused sea urchins to increase and caused the loss of the kelp forests
5. When the loss of one species has a disproportionate effect on the structure and function of ecological communities; Black-tailed prairie dog declines impacted: black-footed ferrets (used p.d. as food), ferruginous hawk (used p.d. as food), burrowing owls (used p.d. burrows)

This theory, postulated by G.F. Gause, describes the situation when two species compete for a limiting resource and one utilizes the resource more efficiently leading to it eventually outcompeting and eliminating the other one. One way organisms avoid this competition is through ____, which will eventually lead to _____, rapid evolutionary differentiation in order to minimize the chances of both competition and hybridization between them.

What terms do we use to describe the species described below. What might be step 4? How does carbon get back into the atmosphere?
1. There is CO2 in the atmosphere
2. The sun provides light energy which is used by a clover _____ to break molecular bonds of CO2 and create chemical bond energy (sugars) via photosynthesis
3. The clover is then are eaten by a rabbit ____ which is eaten by a house cat
4.
Clover: autotrophs – primary producers
Rabbit: heterotrophs- primary consumers
Cat: secondary consumer heterotrophs (carnivores)
4ish: At each stage of energy transfer (plant to consumer) there is death and with consumers there is feces. At each stage there is also respiration which releases H2O and CO2 back into the air. Decomposers process feces and dead plant/animal material.
