Lesson 1 - Biology Flashcards
What are biotic and non-biotic factors ?
Biotic factors are living things in the ecosystem, and abiotic factors are the non-living things in the ecosystem.
What is ecology and what do ecologists study?
Ecology is the study of how organisms interact with each other, and ecologists tend to study and work outside in the environment, rather than working in laboratories.
Describe an ecosystem and biotic and abiotic parts.
An ecosystem with biotic and abiotic parts includes how both biotic and abiotic factors interacts with each other in an ecosystem. For example, the biotic organisms are fish, snake, bird, whereas the abiotic organisms are soil, atmosphere.
What is sustainability and how can it be maintained?
Sustainability is the ability to maintain the resources at a sustainable rate and it can be maintained if everyone on earth starts taking achievable actions as an individual.
Describe sustainable and unsustainable ecosystems
Sustainable Ecosystem is an ecosystem that supports the organisms in a sustainable life
Unsustainable Ecosystem is an ecosystem that is constantly affected by human activities, natural disasters, etc
How do humans impact sustainability?
Humans have huge impacts on spheres such as burning fossil fuels, oil spills, and releasing toxic gases into the atmosphere.
What are each of the 4 spheres and how are they connected?
The 4 spheres are atmosphere, lithosphere, atmosphere, and biosphere. They are connected because spheres do not work alone, but they interact with each other.
What is cellular respiration and photosynthesis, how are they connected?
Cellular respiration is the process in which an organism uses oxygen to break down molecules, and photosynthesis is the conversion of solar energy to chemical energy. They are connected because they are the opposite progresses that compliments each other.
How do human activities disrupt the balance achieved by cellular respiration and photosynthesis?
Human activities such as burning fossil fuels, releasing unwanted trash into the sea, and human chopping down the trees will disruption the balance achieved by cellular respiration and photosynthesis.
Biotic
Living things
Abiotic
Non-living things
Sustainability
ability in maintaining something at a sustainable rate
Ecology
the study of how organisms interact with each other
ecosystem
the interaction of biotic and abiotic factors in a specific area
niche
the role of something
equilibrium
a state which all forces are equal and opposite
Biomes
huge ares with similar temperature and precipitation
Chlorophyll
green pigment that can be found in green plants
Photosynthesis
the conversion of solar energy to chemical energy
Carbon dioxide
an important heat-trapping gas
Glucose
the main type of sugar
oxygen gas
colourless gas at a normal temperature and pressure
Cellular respiration
process of organisms using oxygen to break down molecules
Digestive System
a group of connected organs that work together in human’s body
Respiratory system
structures in human’s body that allows us to breath
Producers
organisms that creates their own food
Consumers
organisms that cannot produce food and must rely on other plants / animals to receive energy
Primary Consumer
animals that only eats plant
Secondary
organisms that eat primary
Tertiary
organisms that eat secondary
Herbivores
animals that only eat plants
Carnivores
animals that only eat meat
Scavengers
animals that feeds on decaying matter
Omnivores
animals that eat both plant and meat
Detritivores
organisms that feeds on and break down dead organic matter
organic matter
decayed plants / animals
predator
animals that lived by killing and eating other animals
prey
animals that are being killed by predator
decomposer
organisms that breaks down dead organic materials
Food Chain
a network of links in a food web
Food web
a connections of all food chains in a community
energy pyramid
a graphic representation of the flow of the energy in an ecosystem
Word Equation for Photosynthesis
carbon dioxide + water + sunlight -> oxygen + glucose
Word Equation for Cellular respiration
oxygen + glucose -> carbon + water + energy
