Assuring a habitat remains unaltered
All organic molecules have what element in common?
Carbon
This element is found in all living things. It is recycled when organisms die. It is transformed from one form to another through photosynthesis and cellular respiration.
Carbon
Most organisms break down sugar to produce usable energy through the process of..?
Cellular respiration
Plantae
Contains photosynthetic organisms that produce their own food supply and yield energy at the base of many food chains
Limiting factors
Controls the populations growth process
Animals
Organism that is made of many parts but cannot make its own food. They are classified by whether they have a backbone or not
Multicellular
Organisms consisting of more than one cell, having differentiated cells that preform specialized functions. Most life that can be seen with the naked eye is this
What is the source of nearly all of the energy for producers and consumers?
Sunlight
Habitat
The area where an organism lives it's life including the living and nonliving factors
Energy
The capacity for doing work. It may be transformed from one to another
Chemical reaction
The changing of substances to other substances by the breaking of bonds in products
Cause
The condition or set of conditions which bring about an effect
Competition
This occurs when 2 or more organisms in a community rely or need similar limiting resources
Animalia
A major group of organisms, that are, in general, multicellular, capable of locomotion and responsive to their environment, and feed by consuming other organisms
Food webs
A representation of the linkages between food chains in a community
What is a major difference between prokaryotes and eukaryotes?
Prokaryotes have no nucleus
Organic
A compound containing Carbon produced by a living thing
Organs
A group of tissues working together to preform a similar function
Chemical energy
Energy in chemical bonds of molecules
Antibiotic resistance in bacteria is the result of?
Genetic variation
The Morphology rhetenor butterfly. The name Morpho refers to the butterflies..?
Genus
What is the most specific classification category?
Genus
About 96% of the information in human DNA is found in gorilla DNA. This evidence supports what?
Gorillas and humans diverged from a common ancestor
Evidence for evolution includes the presence of (blank), which are similar structures shared by different species?
Homologous structures
Family
In biological classification, this is one of the most important ranks. It is more specific than order, but less than genus
Genus
In the classification system, this is a group of organisms with one or more related species
Glucose
Is a simple sugar that provides energy to organisms
Carbon
Is the basis of all living organisms and it is the foundation of organic substances
Any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a (blank) factor..?
Limiting
The process of (blank) increases the genetic variation as it produces gametes for sexual reproduction.
Meiosis
Bacteria
One celled organism that reproduce by fission
Carbon dioxide is returned to the atmosphere primarily by the..?
Respiration of consumers
Which structure or organelle is found in both prokaryotic and eukaryotic cells?
Ribosomes
Ticks suck blood from a host organism. This is an example of?
Parasitism
Classification
Placing an organism in sets of categories based on its characteristics
What kingdom contains only producers?
Plantae
Ecosystem
Populations and abiotic factors with which they interact in the setting of a community
Sexual reproduction
Process by which two cells from different parents unite to produce the first cell of a new organism
Organisms that use energy from the sun to make their own food are called?
Producers
What is an explanation of why producers are always found at the lowest tropic level?
Producers convert light energy into chemical energy
