As a conservationist, you are preparing a report on a frog population living on a mountainside in Costa Rica. In your report, which potential threats to the survival of the species will you predict taking into account environmental abiotic conditions and human activities? a. The frog is at risk from climate change, habitat destruction, and aggressive predators. b. The frog is at risk from climate change, exotic species, and possible habitat destruction. c. The frog is at risk from climate change, habitat destruction, and sparse availability of food. d. The frog is at risk from climate change, exotic species, and over-hunting in its habitat.

d. The frog is at risk from climate change, exotic species, and over-hunting in its habitat.

Key Concepts

Climate Change

This concept involves long-term shifts in weather patterns and temperatures that can alter the natural environment. Such changes can affect species' life cycles, distributions, and ecosystem dynamics, making it a critical abiotic threat to biodiversity.

Habitat Destruction

Habitat destruction refers to the process by which natural environments are ruined or fragmented, often due to human activities such as deforestation, urbanization, or agriculture expansion. This loss of habitat can lead to a decline in species populations and disrupt ecological balance.

Exotic Species

Exotic species are organisms introduced into regions where they are not native, frequently through human actions. These species can become invasive, competing with or preying on indigenous species, and thereby disrupt local ecosystems and threaten biodiversity.

Transcript

00:01 Okay, so now we are going to examine a hypothetical situation.

00:04 We are a conservationist.

00:06 We are looking at some potential species of frog, and we are going to look at which factors, which potential threats would we consider being environmental abiotic conditions and human activities.

00:21 So we need to consider which factors would either fall into those two categories that we mentioned.

00:27 So before we proceed, we need to define and understand what these two categories are so we can categorize the options laid out in front of us.

00:38 So the first category is abiotic conditions.

00:43 So we need to understand what abiotic means.

00:47 Now a good rule of thumb in the english language is if you have a familiar term and a is before it, that is usually a negative, meaning it is referring to the opposite.

00:58 So, aerobiotic is non -living.

01:02 So it's non -living, meaning it is most likely going to be environmental if it's abiotic.

01:15 So some examples of abiotic conditions would be temperature and light.

01:21 So we can think of temperature, light, we can think of water, water conditions that could be an aviotic condition.

01:39 Atmosphere, so air quality, all these things can be considered abiotic conditions because they're environmental and they aren't relating to a living creature.

01:52 So that's how we can think of abiotic in this context.

01:56 So, and then also we're looking at conditions that would be classified as being human activities, right, which is pretty self -explanatory, human activities being caused by humans.

02:10 So i'll just write human, just so we have these two conditions for reference for this question, because that is absolutely essential.

02:20 So we have a few different conditions brought before us, and we're going to look at each one and see if it can be classified in either of the two categories.

02:30 So the first is climate change.

02:32 So climate change, we'll write in green.

02:36 So i'll just put climate, and they'll use the symbol delta which is commonly referring to change in scientific nomenclature.

02:51 So climate change.

02:53 This is both aviotic and potentially human caused.

02:58 So this definitely fits those criteria.

03:02 It actually fits both of them.

03:03 So perfect.

03:04 So another option that we are seeing is going to be habitat destruction.

03:11 So habitat destruction.

03:13 So let's write that in blue for now.

03:17 So habitat destruction.
