6th Grade - Growing and Flowing Vocabulary
Terms in this set (43)
The nonliving factors in an ecosystem. Include things like soil, temperature, amount of water, amount of sunlight. Determines the overall health of an ecosystem. Also determines what kinds of plants and animals will be able to survive and thrive in a habitat.
Any part of an ecosystem that is living or that once was living.
Consists of all life on Earth and all parts of the Earth in which life exists, including land, water, and the atmosphere.
A physical environment with different species that interact with one another and with nonliving things
Ecosystems with specific climates that support specific species of plants, animals, and soil organisms adapted to the climate. Examples are the tundra, taiga, desert, grassland, temperate and tropical forests.
A group of organisms that are closely related and can mate to produce fertile offspring
Place where an organism lives
An organism that can capture energy from sunlight and transform it into chemical energy that is stored as food.
Producers are the main food source for all other organisms in a food chain.
An organism that obtains energy and nutrients by feeding on other organisms or their remains.
Consumers that eat only plants
Consumers that eat only animals
Consumers that eat both plants and animals.
an organism that feeds on the dead bodies of other organisms.
An organism that feeds on and breaks down dead plant or animal matter.
Part of a flower's bloom that are designed to both protect a flower and to attract pollinators.
Leaves found at the base of a flower's bloom. Provides protection for the bloom.
Male reproductive organs of a plant.
Made up of the anther (which creates pollen) and the filament (which supports the anther).
The part of a flower's bloom that produces pollen - the male sex cell that contains half of the material necessary for plants to reproduce.
Female reproductive organs of a plant.
Composed of a long tube that pollen must enter in order for a plant to be fertilized.
The waxy, protective layer often found on the leaves of plants. Designed to slow down water loss through evaporation.
Small holes or pores found on leaves that allow carbon dioxide to enter a plant and water vapor and oxygen to leave a plant.
The process by which green plants and other producers convert sunlight into simple sugars.
Excess glucose is stored in the plant as starches.
Results in the release of oxygen.
The process by which green plants convert stored glucose and starches into energy that can be used for growth.
Results in the release of carbon dioxide.
Simple sugar produced by plants during photosynthesis.
Is the main energy source for all plants.
A survival strategy for plants. A time when a plant does not grow because it is waiting for the conditions (temperature, moisture, nutrients in soil) necessary for survival to reappear.
The tendency of a plant to turn towards - or away from - positive or negative stimuli.
The tendency for stems of a plant to grow away from gravity and the roots of a plant to grow towards gravity.
The tendency for the roots of a plant to grow towards water.
The tendency for a plant to grow towards light.
The tendency of a plant to respond to touch.
A condition that prevents the continuing growth of a population in an ecosystem. Can be the number of predators or prey present in an ecosystem. Can also include the amount of space available in an ecosystem.
A diagram used to show the feeding relationship between a single producer and a chain of consumers in an ecosystem.
In a typical food chain, a plant is the producer that is eaten by a consumer, like an insect. Then the insect is eaten by a second consumer, like a bird.
A diagram that shows a feeding relationship in which many food chains overlap one another in an ecosystem.
A model used to show the amount of energy available to living things in an ecosystem.
The continuous movement of carbon through the Earth, its atmosphere, and the living things on Earth. Carbon enters the living parts of an ecosystem when plants absorb Carbon Dixoide and turn it into Glucose. Carbon returns to the atmosphere when (1). living things break Glucose down during cellular respiration and (2). living things break down and decay.
The continuous movement of nitrogen through Earth, its atmosphere, and the living things on Earth. Nitrogen enters the living parts of an ecosystem when plants absorb it through their roots.
The continuous movement of water through Earth, its atmosphere, and the living things on Earth. Water is stored in both plants and animals -- and is released as a part of cellular respiration and photosynthesis.
Things in an ecosystem that hold onto carbon for long periods of time. Trees, plants and oceans are all carbon sinks.
The process by which plants pull water to their leaves from their roots.
Thin, hairlike tubes inside of a plant that carry water and nutrients from the roots to the leaves.
Thin, hairlike tubes inside of a plant that carry sugars from the leaves to the rest of the plant.
Curved cells around the stomata that squeeze or relax to control the size of the stomata.
A green pigment, present in all green plants that is responsible for the absorption of light to provide energy for photosynthesis.
