Ecosystem
Ecosystem
The variety of life in an ecosystem, often used as a measure of its health.
What is biodiversity? -hc
All the living things and their physical environment with a given area.
What is an ecosystem? -tc
These four types of organic molecules (carbs, lipids, proteins, and nucleic acids) are the building blocks of all living organisms.
What are macromolecules?
This largest part of the brain is responsible for voluntary movement, memory, and thought.
What is the Cerebrum? -hc
What do scientists call the preserved remains or traces of ancient organisms that show change over time?
What are fossils? -hc
The amount of land, water and resources required to support a person or community's lifestyle
What is an ecological footprint? -tc
300 deer live within a 20 km^2 area. 15 deer per square kilometer is the deers ___
What is Population density? -tc
This macromolecule, often stored as starch in plants, provides the primary, short-term energy source for consumers.
What is a carbohydrate? - hc
Known as the “little brain”, this structure located at the back of the skull controls balance and coordination.
What is the Cerebellum? -tc
These structures, such as a human arm and a bat wing, share a common ancestor despite having different functions.
What are homologous structures? -tc
The use of natural resources at a rate that allows them to be replaced or recycled ensuring future availability.
What is Sustainability? -hc
This type of succession occurs after a disturbance destroys an ecosystem but leaves the soil intact, such as a forest fire.
What is Secondary succession? -hc
Plants use sunlight to turn carbon dioxide and water into oxygen and this sugar, which serves as an immediate energy source.
What is glucose? -tc
This brain lobe, located at the front, is responsible for decision-making, planning, and personality.
What is the Frontal Lobe? -tc
Because all organisms use the same genetic code, this type of evidence is considered the strongest for determining evolutionary relationships.
What is DNA/molecular evidence? -tc
Gases such as carbon dioxide and methane that trap heat in the atmosphere, leading to climate change.
What are greenhouse gases? -tc
What happens when a population exceeds carrying capacity?
What is Resources become limited and population decreases? -hc
This term describes the 90% of energy lost between tropic levels, largely due to heat released during metabolism.
What is thermodynamic loss (or heat)? -hc
This part of the brain stem controls involuntary life-sustaining functions like heart rate and breathing.
What is the Medulla Oblongata? -hc
The similarities in early developmental stages of different vertebrates suggest they share this.
What is common ancestor? -hc
A species that is native to a specific restrictive geographical area and is highly susceptible to extinction if that habitat is destroyed.
What is an endemic species? -hc
when an environment has reached its maximum sustainable size for a population, the population growth rate and immigration rate equal what?
What is death and emigration rate? -tc
Lipids provide more than twice the energy per gram compared to carbohydrates, but they are used for this type of energy storage.
What is long-term energy storage? -tc
These are the four main lobes that make up the cerebral cortex: frontal, parietal, temporal, and this one, which processes vision.
What is the occipital lobe? -tc
An example of this type of evidence is the rapid increase in bacteria populations.
What is observed evolutionary change? -hc
