The 7 Life Processes

Flashcards about the Life Processes

MRS NERG

An acronym summarizing the 7 life processes: Movement, Respiration, Sensitivity, Nutrition, Excretion, Reproduction, Growth

Movement

A life process involving the movement of the whole organism or part of it.

Respiration

A life process involving the release of energy from food.

Sensitivity

A life process involving the ability to detect and respond to stimuli.

Nutrition

A life process involving the intake and use of food.

Excretion

A life process involving the removal of waste products.

Reproduction

A life process involving the production of new organisms.

Growth

A life process involving an increase in size or complexity.

Classification

Organising living things into groups based on their similarities.

Taxonomy

The science of classifying living organisms.

5 Kingdoms

Plants, Animals, Fungi, Bacteria, Protists.

Vertebrates

Animals that possess a backbone.

Invertebrates

Animals that do not possess a backbone.

Mammals

Vertebrates with fur; females produce milk for young; warm-blooded and give birth to live young.

Reptiles

Vertebrates with dry scales; cold-blooded; lay eggs on land and breath air.

Fish

Vertebrates that have gills for breathing in water, tails and fins for swimming, and scales.

Amphibians

Vertebrates with moist, smooth skin, that lay eggs in water, start as tadpoles with gills, and develop into adults with lungs.

Birds

Vertebrates with feathers, wings, lay hard shelled eggs on land and have beaks.

Arthropods

Invertebrates with jointed legs, segmented bodies, and an exoskeleton.

Insects

Arthropods with 6 legs, 1 pair of antennae, and 3 body segments (head, thorax, abdomen).

Arachnids

Arthropods with 8 legs and 2 body parts.

Crustaceans

Arthropods with at least 10 legs and 2 pairs of antennae that mostly live in water..

Myriapods

Arthropods with at least 20 legs, many body segments, and 1 pair of legs on each body segment.

Adaptations

Characteristics or behaviors that help an animal to survive.

Behavioral Adaptation

Actions that help an organism survive (e.g., migration).

Food Chain

A diagram that shows the transfer of energy from one organism to the next.

Producer

An organism that uses light energy from the sun to make food through photosynthesis.

Primary Consumer

An organism that eats producers.

Secondary Consumer

An organism that eats primary consumers.

Tertiary Consumer

An organism that eats secondary consumers.

Carnivore

An animal that eats other animals.

Herbivore

An animal that eats plants.

Omnivore

An animal that eats both plants and other animals.

Food Web

A diagram showing many interconnected food chains in an ecosystem.

Endangered

A species at risk of extinction.

Biodiversity

The variety of life in an ecosystem.

Deforestation

The clearing of forests for other uses.

Conservation

Protecting and saving the natural world and all species, in order to maintain biodiversity and protect all ecosystems.
