Ch. 1 Test Flashcards
Organisms that eat only plants
Herbivores
The process of producing food from water, carbon dioxide, and sunlight is called?
Photosynthesis
The movement of digested food and other materials throughout the body of an organism is?
Circulation
The rebuilding of worn out or injured body parts and tissues by an organism is?
Self- repair
The process by which oxygen reacting with food molecules to produce energy needed by an organism to fulfill its life processes is?
Respiration
During excretion the kidneys remove what?
Urea and excess water
During excretion the lungs remove what?
Carbon dioxide and excess water
What is excretion?
The ridding of the body of waste products
Fires, floods; droughts, and storms are what type of stimuli?
Abiotic
An organism that is attached to a substrate and incapable of self moment is what?
Sessile
What is the only life process not necessary for an individual to survive?
Reproduction
Budding, regeneration, and binary fission are what types of reproduction?
Asexual
The acquisition of energy or ingesting food is called what?
Nutrition
The process by which an organism produces offspring through the exchange of genetic material is referred to as what?
Sexual Reproduction
The process by which an organism produces offspring without exchanging genetic material is?
Asexual Reproduction
What is the process by which living things react/ respond to changing conditions in their environment?
Response
The process by which simple substance are broken down through digestion and pass through internal parts of an organism is?
Absorption
The process by which an organism changed from its juvenile stage into its mature form is?
Development
The process by which chemical bonds holding atoms of food molecules are broken down to produce energy for life functions is?
Respiration
The process by which food molecules are moved throughout the body to the individual cells and wasted products are picked up for elimination is?
Circulation
What form of digestion is the process by which food is broken down initially before being ingested?
Extracellular
What form of digestion is the process by which food is broken down within the cells into its component atoms?
Intracellular
The process by which digested food is converted into new living tissue if the organism that consumed it is?
Assimilation
Organisms that consume other things to gain energy
Heterotrophs
Feeds on only heterotrophs
Carnivore
Feeds off both autotrophs and heterotrophs
Omnivore
Organism that is capable of producing its own food
Autotrophs
Type of organism that feeds on the fluids of the internal organs of its host is?
Endo- Parasite
Type of organism that feeds of dead or decaying organisms
Scavengers
Type of organism that feeds in the fluids just below the epidermis if its host
Ecto-Parasite
Autotrophs use sunlight to produce food are using what?
Photosynthesis
Autotrophs use chemicals to produce food are using what process?
Chemosynthesis
During Assimilation simple sugars are converted into what?
Fats, oils, starches, and glycogen
During Assimilation amino acids are converted into what?
Proteins and enzymes
What 2 vessels are involved in carrying food and wastes throughout the body?
Arteries and veins
What does an artery do?
Pumps food and oxygen to cells
What does the vein do?
Pumps waste and carbons dioxide away from cells
What two vessels carry food and water throughout plants?
Xylem and Phloem
What does the xylem do?
Pumps water minerals up from the roots
What does phloem do?
Pumps food down to the roots
An organism uses its 5 senses to pick up what from its environment?
Stimuli
The reaction of organisms to the changes in their environment are?
Responses
The process which a sperm united with the ovum during sexual reproduction is?
Fertilization
Why are life processes of an organism so difficult to detect and classify?
Huge variety of living things, most life processes are internal, many organisms feed internally or camouflage, habitats are hard to reach diverse and hostile, and animals move around are hard to find and often flee
What are examples of extremely diverse, hostile, and difficult to reach habitats?
Deep oceans, mountains, rainforests
