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.
