Vocabulary Chapter 4
A series of more or less predictable changes that occur in a community over time.
What is Ecological Succession
all of the organisms of the same group/ species that live in a specific area and are capable of breeding among themselves
What is a population
What is the Greenhouse Effect
What is when greenhouse gases in the atmosphere allow solar radiation to enter the biosphere. They also slow down radiation back into space.
Draw out where general biome patterns are on Earth (most important, name what kind of biomes do you see at the equator, poles, and in between)
What is tropical at the equator, temperate in between, and polar at the poles.
What are some determinants of population growth?
What are immigration, emigration, death rate, and birth rate
An area classified according to species and climate
What is a biome
What is the population growth calculation?
N= (b+i) - (d+e)
What are three factors that influence the temperature of a designated area.
What are latitude, solar intensity, and the titled axis of Earth
What is a pioneer species? In what situation would you have a pioneer species?
What is the first species to colonize barren land; primary succession events.
What are two ways that you could graph population growth? Draw it on the board and explain the graphs.
**Answers will be drawn out**
environmental conditions within a small area that differs significantly from the climate of the surrounding area.
What is microclimate
the largest number of individuals of a population that a given environment can support
What is a carrying capacity
What is the competitive exclusion principle?
What is no two species can occupy the same niche in the same habitat at the same time.
What are some biotic and abiotic factors for a desert?
**Answers will vary**
Describe human population growth over time.
**Drawn**
What is tolerance
a change in a population from high birthrates to low birthrates and low death rates
What is demographic transition
Name and describe three types of symbiotic relationships.
What are mutualism, parasitism, and commensalism
What are some factors that affect life in aquatic ecosystems (name at least 4)
What are water depth, pressure, temperature, flow and amount of dissolved nutrients, and access to sunlight.
Draw out demographic transition.
**Answers will be drawn**
organisms that live in or on rocks/ sediment at the bottom of lakes, streams, or oceans
What are benthos
Define two types of limiting factors and give examples of each.
What are density-independent and density-dependent limiting factors. Density-independent limiting factors are dependent on the density of the population and events can include competition, predation, disease, overcrowding. Density-dependent limiting factors have an affect that is not dependent on density of the population and include the following examples: natural disasters such as tornados, and human-caused habitat destruction such as logging.
Draw out the Climate Model (hint: what makes up climate and what factors influence climate)
**will draw out on board**
If you lived in an environment that had seasonal drought, mild temperatures, and high winds, what are some characteristics that the animals and plants in the area could have to help them survive?
**answers will vary**
