Flashcards in Life Science Deck (23):
The study that focuses on the relationships & interactions of living organisms & their physical environments.
This is the part of the earth where life exists. It includes water, land, air & covers the planet’s crust where underground creatures dwell to the sky above where birds & other winged animals roam.
These are areas that have similar climates, thus similar kinds of plants and animals survive in them. Factors such as temperature, sunlight, water, soil, and existence of plant eaters determine whether a plant can survive in a certain biome. Food supply, mates, enemies, parasites, and diseases restrict animals to the biomes where they can live. There are 7 major biomes across the Earth.
It is the coldest of all biomes and is located in the northern parts of the world. The tundra has treeless plains as the ground is frozen even underneath the surface.
Located just below the tundra, this biomes summers are short and moist, while winters are long and dry. Mostly evergreen trees are the plants that survive in this type of climate.
These areas have a moderate climate where trees shed their leaves every year. They are found in eastern North America, north-eastern Asia, and West and Central Europe.
There is more grass than trees in grasslands because rainfall is not enough. Examples are the Great Plains of North America and the pampas of South America.
Located near the equator where the sun strikes directly, tropical rainforests have high temperatures and lots of rainfall. Trees in the tropics have thick canopies of leaves to protect them from too much heat.
They are very dry places where water is always lacking. Deserts make up almost a fifth of the entire planet.
The aquatic environment is the largest biome on the planet. It covers three- fourths of the entire Earth.
It is a contiguous system where plants, animals, and other living organisms exist, relate with, and interact with one another and their environment. It may be big or small, clean or polluted.
Are groups of certain species living in a single habitat.
The entire collection of populations is called the ecosystem’s _______.
They are the food producers because they can produce their own energy through photosynthesis.
Plants / Autotrops
They are animals that rely on other sources for their food. There are 3 levels.
Consumers / Heterotrophs
They are herbivores that rely on plants for subsistence. Examples include deer, cow, rabbit, and insects.
They eat primary consumers and sometimes plants. Examples of secondary consumers are shark, lion, and wolf.
Secondary Consumers / Carnivores
They rely on both plants and animals for their food. They are those that eat secondary consumers. They also rely on producers and primary consumers for subsistence. Humans are the most well-known of this type of consumers.
Tertiary Consumers / Omnivores
Bacteria and fungi act as _______ that feed on decaying organic matter to return minerals back to the soil.
Decomposers / Saprotrophs
Certain consumers, such as vultures, jackals, and some insects, also serve as ________ to help in the decomposition process.
This shows the transfer of energy from the producer up to the top consumer. The higher an organism is in the hierarchy of consumption, the less energy it consumes. Dead organisms that are not consumed are broken down by decomposers.
Example of a food chain:
Plankton > Freshwater Shrimps > Small Fish > Big Fish > Osprey
