Hey Aria, Luna, and Olivia! Let's dive into the world of agriculture and wildlife. Have you heard about Dichlorodiphenyltrichloroethane (DDT)? It's an insecticide used in farming. But, it doesn't just disappear; it sticks around in the environment and builds up in fatty tissues, which can be harmful to wildlife. Now, imagine you're studying Ospreys, a type of bird. Based on the information, can you tell which of the following best describes the impact of DDT on the Osprey population?
Option 1: A decrease in DDT will result in a weaker eggshell, leading to a decrease in the Osprey population.
Option 2: An increase in DDT will result in a weaker eggshell, leading to an increase in the Osprey population.
Option 3: A decrease in DDT will result in stronger eggshells, leading to an increase in the Osprey population.
Option 4: An increase in DDT will result in stronger eggshells, leading to a decrease in the Osprey population.

Abigail, Anika, and Elijah are on a field trip to a wildlife reserve. They come across the term 'biomagnification'. Can you help them understand what it means?
It's about how chemical concentrations increase as we go up trophic levels
It's about how chemical concentrations decrease as we go up trophic levels
It's the ability that some animals have to magnify what they see from far away
It's the magical ability of animals
Imagine Arjun, Mia, and Scarlett are having a water fight in their backyard. They're using rainwater, water from washing their car, and water from their garden hose. This water can runoff from their yard. Can you tell us what role this runoff plays in biomagnification?
Run-off is the reason why things run away to new environments
Run-off is how chemicals reach bodies of water where small animals can ingest them
Run-off is a crucial part of the oxygen cycle
Imagine Ava, Elijah, and Benjamin are on a mission to save the planet! Why would it be important for them to monitor environmental parameters when making their planet-saving decisions? Select all that apply.
Imagina que Ava, Elijah y Benjamin están en una misión para salvar el planeta! ¿Por qué sería importante para ellos monitorear los parámetros ambientales al tomar sus decisiones para salvar el planeta? Seleccione todas las que correspondan
To understand how different human activities, like those in their city, affect the environment
To protect the health of their friends, family, and fellow citizens
To evaluate and monitor risks to their mission
To try and decrease sustainability (trick question! They want to increase sustainability)
Anika, Oliver, and Ava are having a debate. They are discussing the term for the gradual increase in the atmosphere's temperature. Can you help them out? What is it known as?
greenhouse effect
global warming
fossil fuels
ice ages
Imagine Jackson, Grace, and Noah are on a mission to save the world from global warming! Which gas from the list below should they focus on reducing to achieve their goal?
Urethane
Oxygen
Carbon Dioxide
Imagine Scarlett, Liam, and Ethan are having a debate. They are discussing which of the following activities contributes the most to carbon emissions globally. Can you help them settle the debate?

Which of the organisms in this food web suffer the most from the effects of biomagnification? (a) (b) (c)
Imagine Benjamin is a scientist and he is trying to measure something. What would we call that 'something' he is measuring?
A parameter
A tool that Noah uses in his mechanic workshop
A type of food that Olivia feeds her fish
Another name for a meter
Maya, Avery, and Ethan are on a mission to save the planet! They are monitoring ECOLOGICAL parameters. But why do you think they are doing this?
Are they doing this to ensure their car parts are up to date?
Or, are they doing this for information, to make predictions, and for evidence on the health of an ecosystem?
Maybe, the parameters help them identify if enough animals are participating in food webs?
Or, do the parameters help them manage when zoo animals are out of their cages?
Imagine Abigail, David, and Aiden are on a mission to save the world! They discover that ecological parameters are used to create laws that protect the well-being of humans and the environment. Is this true or false?
True
False

It decreases the amount of carbon in the atmosphere
It has no impact on the carbon cycle
It increases the amount of carbon in the soil
Hannah, Mia, and Anika are studying for their biology test. They come across a question that stumps them: 'What is the primary reason for the increase in concentration of toxins at higher trophic levels?' Can you help them out?
Because higher trophic levels consume more food
Because toxins are not easily broken down and excreted by organisms
Because lower trophic levels have a higher concentration of toxins
Because toxins are produced at higher trophic levels
Imagine Priya, Maya, and William are on a mission to save the Seal population from the harmful effects of Polychlorinated biphenyls (PCBs), which are industrial products or chemicals. These PCBs persist in the environment, accumulate in fatty tissues, and can cause adverse health effects on wildlife. Based on their research, which of the following best describes the impact of PCBs on the Seal population?
An increase in PCBs will result in a weaker immune system, resulting in a decrease of the population.
A decrease in PCBs will result in a weaker immune system, resulting in an increase of the population.
An increase in PCBs will result in a stronger immune system, resulting in an increase of the population.
A decrease in PCBs will result in a stronger immune system, resulting in a decrease of the population.
