Assuring a habitat remains unaltered

All organic molecules have what element in common?

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

Producers

What is an explanation of why producers are always found at the lowest tropic level?

Producers convert light energy into chemical energy
