Jah is counting all the panthers in the Florida panhandle. This investigation would estimate which factor.
What is population size?

Nitrogen fixation, where gaseous nitrogen molecules are converted into a form usable by plants, is a part of this biogeochemical cycle.
What is the nitrogen cycle?

When a habitat is divided into smaller parcels it is called this.
What is habitat fragmentation?
100
All organisms depend on this trophic level to convert sunlight into consumable energy.
What are producers?

Clear cutting trees causes habitat loss and is called this.
What is deforestation?

Brylin observed that frogs and salamanders both consume dragonfly larva. Frogs and salamanders have this type of relationship.
What is competition?

Kudzu is a rapidly growing vine that is outcompeting native plants in the Southeast US. Kudzu is this type of species
What is an invasive species?
200
Plants evolved to endure conditions of little water. Prickles, waxy leaves, and water storage in roots are examples of these.
What are adaptations?

Acid precipitation is when the atmosphere absorbs excess carbon dioxide and pH lowers. A solution to acid precipitation is to do this.
What is reduce fossil fuels use?

Mya observes that several spiders have built webs and even noticed that there were flies stuck in the webs and wrapped up. The relationship between the flies and the spider is this.
What is predation?

Unlike the carbon and nitrogen cycles, phosphorus cycle does not involve the atmosphere. Plants instead get phosphorus from here.
What is the soil?
300
Herbicides from nearby farms have killed the majority of the plant picture in the food web. The likely outcome to rest of the food web is this.
What is population decrease?
300
Every organism has an ideal set of conditions, like temperature, pH, sunlight, water. The maximum to minimum conditions an organism can endure before adverse effects is called this.
What is tolerance range?
300
Ocean acidification is when the ocean absorbs excess carbon dioxide and pH lowers. A solution to ocean acidification is to do this.
What is reduce the burning of fossil fuels?

Ashlyn noticed when the alligator population changes, so did the populations of several other species. She likely hypothesized that the alligator is what type of species.
What is a keystone species?

Carbon atoms enter biotic systems through this process.
What is photosynthesis?

Hypothesize what may happen to the chipmunk population should the foxes die off from overhunting.
What is population increase?

The crop most tolerant to acid rain.
What is Alsike Clover?

Biomagnification is the process of toxins accumulating and increasing in concentration up the trophic levels. A solution to biomagnification includes this.
What is reduce toxin pollution and avoid certain animals as food sources?

Jada noticed an overpopulation of robins in the environment. The robin population then came back down after the overshoot. She now hypothesizes that the robins are back at the maximum steady capacity called this.
What is carrying capacity?

The plant has 4000 units of energy; assuming the 10% rule, the fox can get this much energy.
What is 40 units of energy?

A new factory has been developed by a waterway and a drastic increase in carbon dioxide has been measured in the ecosystem. Hypothesize the likely outcomes of this change.
What is acid rain or ocean acidification?

Pictured is a plant growing in response to gravity. When plants grow in response to light, it is called this.
What is phototropism?
500
Eutrophication is releasing fertilizers and sewage into waterways increases the phosphorus and nitrogen in the water. This influx of nutrients feeds the algae, and they overpopulate and use up the oxygen. A solution to eutrophication is this.
What is reducing fertilizers and sewage in the water, and cleaning the algae and water?
