This term describes a plant or animal that enters an ecosystem where it doesn’t naturally belong and can cause harm

Invasive species

100

This term describes the buildup of harmful substances, like pesticides, in an organism over time.

What is bioaacumulation?

100

This particle, found in the nucleus of an atom, has a negative charge and nearly no mass

What is an electron?

100

Weather is what happens in the atmosphere daily, while this term refers to the average weather over a long period.

the climate

100

This natural process keeps Earth warm by trapping heat in the atmosphere.

what is greenhouse effect?

200

If an invasive species is introduced into a food chain, it can lead to a decrease in this group of organisms, which are typically preyed upon by native predators.

Native species of herbivores/primary consumers/secondary consumers

200

This process causes the concentration of harmful substances to increase as you move higher up the food chain

What is biomagnification?

200

This part of the atom is made up of protons and neutrons and is found at the center.

What is a nucleus of the atom?

200

The early Earth's atmosphere was mostly made of gases like carbon dioxide, methane, and this gas, which makes up most of the current atmosphere.

Nitrogen

200

Burning fossil fuels like coal, oil, and natural gas increases the levels of this greenhouse gas in the atmosphere.

What is carbon dioxide?

300

The introduction of the cane toad in Australia is an example of an invasive species causing harm by doing this to predators who eat it

What is poisoning or killing them by poisoning?

300

Organisms at the top of the food chain, like eagles or sharks, are most affected by this process because they eat many organisms containing toxins.

What is biomagnification?

300

This scientist is known for discovering electrons using a cathode ray tube.

Who is J.J. Thomson?

300

These ancient organisms were among the first to perform photosynthesis, releasing oxygen and dramatically changing the Earth’s atmosphere.

Cyanobacteria

300

This type energy sources like solar and wind power are better for the environment because they don’t produce large amounts of greenhouse gases. 

Renewable energy sources

400

Invasive species can disrupt ecosystems by competing for these, such as food, water, and shelter, often leaving native species without enough to survive.

What are resources?

400

In bioaccumulation, toxins are stored in an organism’s body, rather than being undergoing this process.

What is being broken down/ decomposed?

400

This scientist created a model of the atom in which electrons orbit the nucleus in specific energy levels

Who is Neils Bohr?

400

This process, used by early photosynthesizing organisms, converts carbon dioxide and water into glucose and oxygen, significantly increasing the oxygen levels in the atmosphere.

What is photosynthesis?

400

In comparison to on-renewable energy sources that can run out this is one advantage of renewable energy.

sustainable, replenishable, or unlimited
500

term for the interdependent network of plants, animals, and microorganisms in an environment that invasive species can disrupt

What is an ecosystem

500

When a pesticide enters a pond, it first accumulates in small organisms like plankton. Name the other levels of the food chain that might eventually suffer due to biomagnification.

What are fish and birds (or top predators)?

500

Ernest Rutherford’s gold foil experiment showed that most of the atom is this

what is empty space

500

The buildup of oxygen in the atmosphere, caused by photosynthesizing organisms, led to the formation of this protective layer that shields Earth from harmful ultraviolet radiation.

Ozone layer

500

One con of renewable energy sources is that they depend on natural conditions. For example, these two type of energy works only when the sun is shining or relatively stronger tides.

Solar energy and tidal energy
