Lesson 9.1 Flashcards
All living things in the ecosystem need
energy
the transfer of energy loses most of its usable energy as heat; thus, energy never returns to the sun, and therefore, it is impossible for energy to cycle because it dissipates into the surrounding;
entropy
All matter in the ecosystem are made up of tiny particles called
atoms
The animals grow and survive by getting their nutrients from
plants
Plants also grow by getting nutrients from the
soil
Energy does not cycle through ecosystems; instead they move in
another direction
is comprised of trophic levels in which
the energy is transformed.
food chain
the ultimate source of energy on planet Earth.
energy from sunlight
green plants can manufacture organic compounds as sources of energy and nutrients
producer
get their nutrients and energy by feeding directly or indirectly on plants.
consumers
1st level consumers, are animals or insects whose primary food source is plants
herbivores
(Flesh eaters) are secondary consumers which feed on plant-eating animals.
carnivores
tertiary consumers, which feed on plants, herbivores, and carnivores.
omnivores
such as bacteria and fungi break down dead tissue or wastes and absorb their soluble nutrients
Decomposers
refers to the interconnected or interlocking relationships among various food chains in an ecosystem. Living things may feed on several members of the web
food web
Grazing food chain starts from _________
green plants to the grazing herbivores then to the carnivores
Detritus food chain starts from ____________ such as beetles, ants, and earthworms, and their predators.
decaying matter to microorganisms then to detritus-feeding organisms
2 classifications of food chain
Grazing food and detritus food chain
the most essential abiotic factor which helps most living things survive.
water
the lifeblood of Earth. It is an essential part of all living
water
Hot temperature in the atmosphere produces ____ moisture
greater
the heat and cold equilibrium in combination with many environmental factors
temperature
the main source of energy for all plants and algae
light
has an important part to play in the life of many living things
natural light
Humans need ____ to become healthy.
light
due to the gravitational force of Earth in which the atmospheric gases are pulled toward the surface which produces air pressure.
Atmospheric pressure
such as carbon, oxygen, hydrogen, and nitrogen, are essential elements of life
chemical components
Organic and inorganic compounds are derived mostly from
plants and other food sources
Out of the __ naturally occurring elements on Earth, ___ of which are found in living things.

All organisms have their own way of adapting that helps them survive and thrive.
adapting
_____ happens when a gene mutates or changes by accident.
Adaptation
_______ refers to the physical characteristics of an organism that help them to survive in its ecosystem
Structural adaptation
They change the color of their skin to deceive their enemies by blending with their environment. This type of behavior of an animal is known as _______
camouflage
During winter, in some parts of the world, some mammals _____ because of cold weather;
You sent
hibernate
animals that live in deserts like squirrels and some insects go into a kind of deep sleep during summer instead. This sleep is called ______
estivation
A plant adaptation that is sharp, pointed structure, and for protection
spine or thorn
A plant adaptation that is long, thin, and coloring structure. For support and climbing
tendril
A plant adaptation that is thin and long; attached to the stem. For support
prop root
the wealth of humans
wide variety of plants and animals
The sum of all the different species occupying a wide variety of ecosystems and the foundation of life on Earth is called ____
biodiversity
Many species live on ____ than in the ____
land > sea
It refers to different biomes
Ecosystem diversity
The______ and ____ is of great importance in the field of medicine, food industry, and agriculture
biodiversity of flora (plants) and fauna (animals) i
________ is a source of test organisms’ samples in conducting research studies to discover things for wellness.
Biodiversity
