Populations and Ecosystems
This is the term for all the members of the same species living together in an area.
Population
In a food chain, this is the term for an organism that makes its own food, usually using sunlight.
This is the term for a characteristic or behavior that helps an organism survive in its environment.
Adaptation
True or False: She was the first woman to win a Nobel Prize and the only person to win in two different scientific fields.
True
This scientist is credited with creating the first widely recognized periodic table in 1869.
Dmitri Mendeleev
This type of factor in an ecosystem includes living things like plants, animals, and bacteria
Biotic factors
This is the term for an organism that gets energy by consuming other organisms.
Consumer
A species that is no longer found anywhere on Earth is said to be this.
Extinct
Marie Curie discovered this radioactive element, which she named after her homeland.
Polonium
Mendeleev arranged the elements in his periodic table primarily by increasing this property.
Atomic mass (weight)
This is the term for the non-living factors in an ecosystem, such as sunlight, water, and soil.
Abiotic factors
A food web shows the feeding relationships between organisms in an ecosystem. These organisms break down dead matter and recycle nutrients.
Decomposers
This is the term for the variety of life forms in an ecosystem.
Biodiversity
Along with her husband Pierre, Marie Curie conducted groundbreaking research on this element, known for its use in cancer treatment.
Radium
The periodic table is organized into rows called this, which represent different energy levels of electrons.
Periods
The maximum population size that an environment can sustainably support is called this.
Carrying capacity
This is the term for the position an organism occupies in a food chain, such as primary consumer or apex predator.
Trophic levels
This process occurs when organisms better adapted to their environment survive and reproduce more successfully.
Natural selection
Marie Curie's research contributed significantly to the development of this field of science focused on the study of radioactivity.
Nuclear Physics
Elements that are in the same column of the periodic table share similar chemical properties and are called this.
Groups or families
This term describes the role and position a species has in its environment, including all its interactions with biotic and abiotic factors.
Ecological niche
Energy in an ecosystem decreases as it moves up the food chain. About this percentage of energy is passed from one level to the next.
10%
This type of adaptation involves physical features of an organism, such as the long neck of a giraffe or the webbed feet of a duck.
Structural adaptation
Marie Curie's work on radioactivity laid the foundation for this medical technique used to treat diseases, including cancer.
Radiation therapy
This is the term for a change in matter that produces one or more new substances, such as burning wood or rusting iron.
Chemical reaction
